>> I'm looking for a way to dynamically determine a HLL (RPG, CL, etc) interface in terms of parameter counts and data types. Not possible Paul (well as close to impossible as makes no difference anyway). _If_ the program was compiled to produce descriptors (RPG always produces minimal descriptors, COBOL doesn't unless you request it) you would be able to determine the number of parms passed. However, operational descriptors are a half-assed implementation which Rochester has never completed. Consequently there are very few parameter types that can actually be determined. So other than determining parameter count it is fundamentally useless. The architecture does not provide for any external description of the parms passed/expected - sadly. Makes it real tough to write truly generic routines. The closest you can get is to have the compilers generate the PCML for you. Unless you want to develop a tool that dumps the instruction stream and reverse engineers the code to determine the (probable) parameter type and size. I doubt that's on your list of things to do before supper <grin> Jon Paris Partner400 www.Partner400.com www.RPGWorld.com
