Two new enhancements related to generating PCML

barbara_morris Visits (1461)

If you get the compiler to generate PCML for your module or program, you may have been annoyed at the way the procedure and parameter names in the PCML were in uppercase. Or you may have been frustrated because one of the procedures in your module has features that are not allowed for PCML generation, which caused the compile to fail. If you didn't need PCML to be generated for that particular procedure, you had to split out some of your... [Continue Reading]

barbara_morris Visits (1754)

There are two new enhancements for RPG, available through PTFs. These enhancements are timed to coincide with 7.2 TR1 and 7.1 TR9. First, the ALIAS support that was new in 7.1 is now extended to support all externally-described files. Second, the rules for using result data structures for I/O have been relaxed, allowing you to use the same data structure for both input and output operations. Read here,... [Continue Reading]

Are you using OPTION(*NOUNREF)? If so, good! If not, read on.

barbara_morris Visits (2432)

If you're not already using OPTION(*NOUNREF), I recommend that you consider doing so. OPTION(*NOUNREF) was introduced in 6.1. It tells the compiler not to generate unused fields into the module. By default, with OPTION(*UNREF), the ILE RPG compiler generates unused fields into the module. Prior to 6.1, you had no control over this. The default *UNREF has some negative effects. Too much storage for the module The most common ways for a module... [Continue Reading]

New version of the wiki article on converting C prototypes to RPG

barbara_morris Visits (1850)

The article on converting C prototypes to RPG has had a major overhaul. https://ibm.biz/BdxQbC The old version was written from a pre-V5R1 perspective, with some remarks about post V5R1 or 6.1 coding. The new version is written from a 6.1 perspective, using QUALIFIED and TEMPLATE as a matter of course, with some side remarks about how to handle TEMPLATE in pre-6.1 coding. All the discussion about pre-V5R1 coding has been removed. Also, the... [Continue Reading]

Did you ever get weird errors after you called an API?

barbara_morris Visits (1704)

Here are the top 3 mistakes I see people make that can cause storage corruption. Storage corruption can then cause strange and sometimes intermittent errors to occur. Mistake: Not passing the feedback parameter for CEE APIs When the API documentation says a parameter is "omissible", it means you can pass *OMIT as the parameter. It doesn't mean you can completely leave it out. On your RPG prototype, code OPTIONS(*OMIT). When you pass... [Continue Reading]
