Transitioning from other COBOLs
The isCOBOL Compiler and Framework have been proven to compile and run successfully source code from the following COBOLs that were not discussed in the previous transitioning guides:
COBOL | Advice |
|---|
Fujitsu NetCOBOL | |
Hitachi's COBOL | |
HP COBOL | |
LPI-COBOL | This COBOL is very similar to RM/COBOL, so you should consider following the advices provided in the Transitioning from RM/COBOL guide. |
OpenCOBOL/GnuCOBOL | |
VMS COBOL | |
COBOL-IT | |
Data Access
• Fixed length sequential and relative files coming from the above COBOLs are fully supported by isCOBOL.
• Indexed files from the above COBOLs must be converted either to c-tree or JIsam with the following steps:
a. unload file data to a raw binary file with the tools provided by the other COBOL vendor
b. create an empty c-tree or JIsam indexed file by running a program that performs opens the file for output with isCOBOL
c. load data from the raw binary file into the empty indexed file with
ctutil or
JUTIL.
