Abstract--The program GENETAB draws stratigraphic range charts from information in any type of geologic database. It provides output on a standard microcomputer printer. The version described in this paper permits the use of data from Mesozoic strata, and draws cooccurrence intervals of both precise and imprecise ranges. The program is written in BASIC, and accepts input from dBase files.

Key Words: BASIC, Biostratigraphy, Range charts, Mesozoic.

INTRODUCTION

Paleontologists may have to draw stratigraphic range charts. Such charts assist with definition of the stratigraphic range of a taxon, or clarify the age of a sample that includes several taxa. This drafting may be tedious, and the result may not be revealed until final stages of the stratigraphic work.

The program GENETAB provides a quick way to obtain a printed graphic interpretation from a data file (STRATI. TXT) containing taxonomic and stratigraphic information about specific taxa. The program also provides a cooccurrence interval of the taxa sought. The program GENETAB is written in BASIC (BASICA), and can be compiled with the BASCOM compiler. It has been implemented on a IBM-XT with 256kbyte RAM. The output from the program is formatted for a 80-column wide printer, working with Epson control code. As it is listed here (Appendix 1), GENETAB works with Mesozoic strata, and the record numbers in the STRATI.TXT file are limited to 500. Minor modifications in the initialization lines allow use of taxa of other era.

Some programs and methods concerned with range charts (Edwards, 1978; Dienes, 1978) have been published already. They handle well-sampled sections and assist to draw local range charts. GENETAB differs from them by being concerned with bibliographic data and shows the present state of know- ledge on one or several taxa ranges.

INPUT FILE: STRATI.TXT

The data file read by GENETAB has to be named STRATI.TXT. It is a sequential file readable in BASIC. GENETAB does not assume the creation of this file. In our application this file is a result from a selection within a database written in dBase III. The database program is not described here but is avail- able from one of the authors (B.V.) on request. Each record of STRATI. TXT has ten fields. An example of the input and its format is shown in Appendix 2.

Fields CI -C4 keep taxonomic data. CI holds the genus group name, C2 the species group name, C3 the taxon author name, and C4 the name of the author and the year of the bibliographic reference.

Fields C5-C10 contain stratigraphic data, three fields for the appearance and three for the disappearance levels. The reason for this is that in a section both the appearance as well as the disappearance of a taxon can be observed in either a "well-dated" level or in a "presumed-age" level (Fig. 1). In the latter situation it might happen that, at either the top or the bottom of that strata, a taxon occurs in finely dated levels. Also, both range end points may be imprecise. The data definitions of fields C5-C10 therefore are formed as follows:

C5 : age of the lower boundary if it is the same as the section one,

C6 : age of the lower boundary if this age is imprecise,

C7 : age of the lower boundary if this age is well established or age of the first level well dated,

C8 : age of the upper boundary if this age is well established or age of the last level well dated,

C9 : age of the upper boundary if this age is imprecise,

CI0: age of the upper boundary if it is the same as the section one.

It will be obvious that fields C5-C10 cannot be filled at the same time. It also is illogical to name data in fields C5 and C6 as well as in C9 and CI0 at the same time. On the other hand, if there is data in field C7, there must be data in field C8 and vice versa.

The data format in the stratigraphic fields is com- posed of three alphanumeric and one numeric characters (e.g. "Bat l") . The alphanumeric characters cor- respond to the three first letters of the stage name. The numeric characters range from 1 to 6, representing an arbitrary subdivision of a stage. In a sample, "Ba t l " indicates basal part of Bathonian, "Ca l 5" base of the upper part of Callovian. The user has to correlate these subdivisions with his own. A simple modifica-

tion of the program would allow stages to be sub- stituted by zones.

PROGRAM

GENETAB is made of three parts of which the second one calls a subroutine. After the variable initialization, and the reading of the "chronological order relation" array, the data file STRATI. TXT is read. The next step in the program GENETAB is to create the output file, termed FICHOUT. Finally the program prints the results.

The use of the chronological order relation array One of the characteristics of GENETAB is the use

of a chronological order relation. To make the stratigraphic data collection easy, they are put in as alphanumeric characters. For this purpose an array (TEM$ (I)) is created (lines 1200-1260). Each geologi- cal stage (or zone), represented by a string made of its three first letters, corresponds to the array-element of which the ' T ' value equals the stage chronological order.

This array is used twice, first to check for the order of the oldest and of the most recent stages recorded in data file (lines 1610-1680), and secondly, to make the stratigraphic data numeric (lines 2300-2380).

As described here (Appendix 1), the oldest stage is the Scythian (TEM$ (1) = "Scy") and the most recent the Maestrichtian (TEM$ (28) = "Mac"). To adapt GENETAB to another era than the Mesozoic, this array has to be modified with respect to the relation of the chronological order.

Writing output file FICHOUT The first reading of STRATI. TXT gets the par-

ameters of the chart dimensions: NBFI, CTAX,

boundaries. Taxon occurs strata for which we have Cenomanian strata.

TMIN, and TMAX (lines 1350-1690). From these values, NCOL (width of chart in character columns) and NTABL (number of chart lines) are calculated (lines 1710-1790). Because NCOL can be bigger than 80, and even than 132, and because the GENETAB is written to run with a 80 characters/line printer, the chart has to be printed in several (NBLO) blocks, each of 80 characters width. This constraint has been sol- ved with a specific input subroutine that opens a direct access file called "F ICHOUT" , which stores records in 80 characters width. When a chart line is built, this subroutine (lines 3160-3250) puts the first 80 characters in the record of which the order (D) equals the table line one (NOLTAB); then, up to the end of the range-chart line, it puts the next 80 characters in the record number D where D = D + NLTAB. Written in this manner, F ICHOUT can be printed from record 1 to record N. The successive printed blocks have to be put side-by-side to obtain the final range chart.

Building of chart-data lines The data lines are made of two parts: the left one

with the taxonomic data and the right part with a graphic interpretation of the stratigraphic data. Each line corresponds to a record of the STRATI. TXT file. The taxonomic part is made by the simple concatena- tion of the fields C I - C 4 data (lines 2170-2180). The right part construction is a little more specific. The goal is the stratigraphic data transcription in a string made of characters as "-", "x" and "?" (Table I). The part made of "-" indicates imprecise range; part with "x" well dated range; the "?" indicates that we do not know if the range is bigger than the written one. Therefore we first have to make the data numeric (lines 2210-2370). In the same command lines we put at 1 the boolean Ci i fda ta occur in the C(i + 4)$ field. Then we calculate the positions (B1-B6) of each

Editing stratigraphic range charts

stratigraphic data on the range-chart line (lines 2390- 2430). At last the transcription is written. First, a string made o f " - " between the lower and upper limits is stored, then it is modified as a function of the boolean C3, C1, and C6. If C3 equals 1 (we need not test C4, because it is identical to C3) that indicates that we at least have a part of range which is well dated; thus between the positions B3 and B4 the previous string is replaced by a string of "x" characters. At last, if C1 and/or C6 equals 1, "?" is put on BI and/or B6 positions.

Building o f cooccurrence line The cooccurrence line shows the overlap in range

for all the recorded references of all taxa from the "STRATI. TXT" file. The time limits of this line are the most recent appearance (LI) and the oldest disappearance (LS). For a more precise interpretation of the time limits for the cooccurrence line, information about the most recent "well-dated" appearance (BI), the oldest "well-dated" disappearance (BS) as well as information about the oldest appearance correlated with the base of the section (DD) and the most recent disappearance correlated with the top of the section (FF), need to be known. For each record read from the data file, comparisons are made for the appearance/disappearance variables (lines 2570-2710). As a final stage in the interpretations of the cooccurrenee lines, the program tests if the interval, (1) exists, (2) exists, but is not precise, or (3) does not exist.

The situation, when an overlap in range does not exist (3), occurs when the appearance on one line is younger than the disappearance on another, that is when at least two taxa do not cooccur. For this situation LI is greater than LS, and both have lost their initial value. The graphic interpretation of this situation is a string o f "0" (the range is empty) between the position of LS and LI (line 2830) (Table 2).

In the second situation, when the interval exists, but is nonprecise, both CI and C6 are equal to 1 in all records. On the table, data lines for all extreme limits are marked by a "?". This situation can be tested because in such a condition the command lines 2600 and 2660 jump the modification of LI and LS. Thus if both LI and LS have kept their initial values, the cooccurrence interval cannot be precise; a string made of "8" and limited by DD and F F indicates that situation (Table 3).

In the third situation and in this one only, LI is

793

inferior or equal to LS. It has been made possible to point out the quality of the cooccurrence interval. The quality is indicated by using different characters (Table 4): the character " = " indicates that on its column there is only "-", the " + " character indicates that on the column we have "-" and "x" characters, at last "H" indicates that on its column we read only "x" characters. To build such a string we have to take into account the characters written in the data lines. To reach this goal a string made o f " = " characters is stored; then, after reading in each data record for which C3 equals 1, the part of this string between positions B3 and B4 is replaced by a string of " + " characters (line 2700). At last we get on this string the part between position LI and LS and place it on the range-chart line at the same position (line 2830). At this point the graphic interpretation is made of " = " and " + " . It must be tested now if some " + " have to be replaced by "H". This change has to be done if BI is less than or equal to BS and EG equal to 0. The second condition is true if all data records in the fields C75 (and C85) contain data in other words if there is a string made o f " x " in all range-chart lines. The "H" string has to be written between the positions BI and BS but in the interval LI-LS, therefore its limits de- pend on the positions of BI and BS in regard to the LI and LS positions; the different eventualities are treated in lines 2850-2890.

RANGE-CHART PRINT

The "F ICHOUT" file is printed as a sequential file (lines 2980-3080). The printer control codes are used to save paper if the range charts are small and to individualize the different blocks so as to make their assemblage easy.

LPRINT CHR$ (27); "C" CHR$ (n); set page length at n lines,

LPRINT CHR$ (27); "N"; CHR$ (n); selects skip- over perforation for n lines,

LPRINT CHR$ (10); advances the paper one line.
