| We want to migrate to the current version of PLI (installed base + 11 million loc) . The old version is running in a compatibility mode already. We would like to switch to ""full function mode"" at the same time. Is there any experience to be able to anticipate on certain consequences? |

Enterprise PL/I is a lot stricter with regards to iffy code that worked in older versions, it's not impossible that you get rather a lot more warnings.
One of the better ways to handle migration is to change your compile JCL to use both compilers and copy the 4.1 listing the default-named listing if 4.1 throws up anything of severity >= 8.
Once 4.1 is standard, start tightening the screws using things like:
| Code: |
rules(noevendec nogoto(strict));
rules(noglobaldo nolaxbif nolaxctl nolaxdcl nolaxdef);
rules(nolaxentry nolaxif nolaxinout nolaxlink);
rules(nolaxmargins(xnumeric) nolaxpunc laxqual laxscale);
rules(nolaxsemi nolaxstg nolaxstrz nomulticlose nopadding);
rules(noprocendonly nostop nounref); |
and
| Code: |
maxgen(2048);
maxnest(block(4) do(4) if(4)); |
and
| Code: |
| deprecate(builtin(date)) |
