There is no published API to list program procedures because they are 

not visible outside the program object (i.e., you cannot export program 

procedures like service program procedures or module procedures). Since 

they are private to the program there is little point in listing them. 

This is also true of private service program procedures. The published 

APIs list only the public (exported) procedures.


The only way I know of to determine the procedures used in a program is 

to examine the module string directories in the program object. Note 

that these appear to contain all procedures **USED** in the program, 

not just those **DEFINED** in the program. I suspect they also contain 

exported and imported variable names but I have not verified that 

supposition.


I do not know of any way to determine the procedures defined in modules 

used by a program object except by interrogating the original module 

object via the published API. If you no longer have the *MODULE objects 

then this will not help.
