Mantis Conversion

Complicated & Thorough Process Several issues need to be addressed

in the analysis stage These issues are discussed and

resolved with the User

Basic Conversion Issues

MANTIS is a robust and forgiving language– Define files, maps & routines that do

not exist– Define datanames in the in-line code

These are illegal in COBOL!



Conversion - Analysis

Check for Redundant Code Re-iterative Process Run until no redundant code

remains Redundant code retained as

comments




Completeness check Do all referenced components exist? Files, Screens, Programs etc. Passed back to user for resolution






Component Name Resolution MANTIS allows much longer names MANTIS names can user Cobol

reserved words?

These must be resolved Conversion has defined defaults,

but user has option to override






Check for code validity? MANTIS allows programs to address

data areas that are outside bounds? Array of 10 MANTIS let’s you

reference 11, COBOL doesn’t! Field of 6 bytes, MANTIS let’s you

reference byte 7, COBOL doesn’t!Must be resolved!



Now the CONVERSION!

Only when all the analysis issues have been resolved are we ready to commence the actual conversion!



CONVERSION

User Mantis Screens are converted to BMS MAPS

User is provided with source of BMS maps to assemble

User is provided with Cobol Copybooks for the maps





CONVERSION

User Mantis File, Database and Interface layouts are converted to Cobol layouts

User is provided with appropriate Cobol Copybooks



CONVERSION

User Mantis Programs are converted to CICS Cobol

User is provided with clean compiled Cobol source

All code produced is 100% pseudo conversational



Code Sample - CONVERSE



Code Sample TXT function



Code Sample - Logic



Initial Code Impressions

Taken from a small sample Many long component names, but

this is easily addressed No “out of bounds” errors No “DO” of missing routines No “Dynamic Screen Placement”

e.g. CONVERSE MAP1(XROW,10)



Conversion - Testing

Good quality on-site engineers Cobol & MANTIS knowledge Business Knowledge CICS expertise (CEDF skills) Access to debugging software
