Just wondering if anyone has gone through this process previously? One of our clients is about to go through 4.2 => 6.2, and the presentation looks like we're going to have a lot of work (as we provide PS for them for our software).
I figure it's going to involve some fairly intensive compiling to determine coding issues and some meticulous testing to make sure we don't have any hangover data issues. But if anyone has any horror stories, please feel free to elucidate! |

| We recently upgraded from COBOL 5.1 to 6.2 and experienced almost no issues. We had to look closely at the site default table as there were a number of changes to it that we had to review, but the applications programmers did not encounter any major issues. |

From my stand-point, I'm guessing that we'll not only have some TRUNC(BIN) issues, but also some data issues (where there are spaces in PIC 9 areas) in the client files.
The code itself is probably (mostly) OK, but we've got well over 20,000 pieces in our software puzzle, so I'm sure something has crept in over the years. Not to mention some of our third-party suppliers have not yet upgraded (checked) their COBOL to be 6.2 compliant.
Have you noticed any major increase in compile times? The presentation from IBM indicated this could be significant. |

Hello Team,
I am currently working on a Cobol Upgrade requirement from Cobol 4 to Cobol 6.2. In the regard, i could get many details from IBM Cobol 6.2 Upgrade manual, but I am not confident on the target compiler options to be used for Cobol 6.2 program as compared to Cobol 4 programs. Can anyone help me with passing the information as to what compiler options should we keep for below compiler options after upgrading to Cobol 6.2 programs:
Cobol 4 version compiler options as below:
LIB,
OBJECT,
RENT,
APOST,
DATA(31),
OPT(FULL),
SIZE(MAX),
BUF(8K),
LIST,
S,
LANG(UE)
Regards,
Arun |
