That idea makes passing the parameters into a two step operation.
1. write the file containing parms
2. write the call referencing the file

you are correct, Harry: doing it that way
I don't have to worry about the translation from parm=value
to macro variables

the issue are:
* what delimiters to use between multiple parms
  I saw examples using comma
  semicolon seemed a natural choice
* how to move information in sysparm
  to actual use in program

for my case global macro variables are
the appropriate choice before calling a parameterized include file
one of my examples below shows passing the macro call in sysparm
I think we went round and round to discover that one cannot have
a percent sign as first character of sysparm
thus' -sysparm ';%DoThis(parm1=x)'

the reason I asked is because
I have started doing R&D for abstracts for fall SUG paper(s)

I had posted a note earlier about a suggestion to write calls to a .bat
file

http://www.listserv.uga.edu/cgi-bin/wa?A2=ind0702B&L=sas-l&P=R23665

using that idea and the code posted beginning this thread
I have a written a caller for my FreqAll routine
for every member in a library.

I am always amazed at how little code it takes
to do umpteen iterations of a large process.

here's the output from the driver program
- - - FreqAll-exec-calls.bat - - -
rem     28FEB2007:09:56:04
call sas FreqAll-call-one -sysparm 'in_lib=SASHELP;in_data=ACCBW' -print
..\lst\ACCBW.lst
call sas FreqAll-call-one -sysparm 'in_lib=SASHELP;in_data=ACCBWMT'
-print ..\lst\ACCBWMT.lst
...
call sas FreqAll-call-one -sysparm 'in_lib=SASHELP;in_data=ZTC' -print
..\lst\ZTC.lst
