When I precompile my pcl codes using cpp.exe provided by Patran 2020, some mistakes occurr. But everything is OK when I use cpp.exe provided by Patran 2016. I guess some rules of the precompiler have changed. I wonder, what updates the new compilers(cpp.exe and p3pclcomp.exe) have made? Is there a convenient way to migrate my old PCL codes for the new compiler? Can the .plb I compiled with the latest compiler run on the old Patran version?

What is the difference between CPPs provided by Patran 2016 and Patran 2020?

Unfortunately this is a bug. You should continue to use the older version of cpp.exe for now (versions up to Patran 2019FP1 should be OK).

It only affects cpp.exe - there are no changes to p3pclcomp.exe and new plbs will still run on older Patran versions.

Thank you very much for your reply.

I have added two other examples for your reference, see the previous attachment，CPP_TEST3，CPP_TEST4.

One more question. If the C language static link library provided by Patran is used in my program, such as libaccess.lib, do I need to use the corresponding link library on each plug-in corresponding to Patran version, or do I only need to use the latest libaccess.lib, then my program can run on all the old Patran versions?

Thank you for the additional examples - that's helpful.

On libaccess.lib, I believe that it's version-dependent. However I don't have experience of this and I'm not 100% sure that's correct.
