RE: How to prototype CL modules

[Chris Bipes <chris.bipes@xxxxxxxxxxxxxxx>]

I like the idea of the Parameter Group as you suggested.  Your syntax even
looks good.  When are you going to work with Hans?

IBM must have this somewhere.  For example check out the Data Queue APIs,
they have groups.  If you want to pass one parameter in the group, you must
pass all in the group.  whether it is controlled at the application level or
system level I do not know.  The application level is easy "if #Parms > x
then use x, x+1 endif" "if #Parms > y then use y, y+1, y+2 endif"...

System level or Compiler level would be GREAT!

Hello Barbara,

I haven't yet made up my mind on this.  I don't know any HLL that allows
those sorts of 
related definitions.  My view tends to be that since the API itself enforces
the 
parameter requirements omitted parameters from a group will be caught during
Unit Test.  
The purpose of the prototype is to ensure that IF a value is passed it is at
least of the 
correct type and length.  It is the programmer's responsibilty to ensure the
proper 
parameters are actually passed.  Although it's a good idea, perhaps what we
need is a 
Parameter Group tag so we could code:

/if defined(LONG_PROC_NAMES)                                              
 QmhSndPgmMsg    PR                                                       
/else                                                                     
 QMHSNDPM        PR                                                       
/endif                                                                    
                                     EXTPGM('QMHSNDPM')
