[gradsusr] Anyway to have a 'master' file that gets included before anything else in a .gs file?

[Jennifer Adams]

> cat yourMainScript.gs
function main(args)
rc=gsfallow("on")
parseargs(args) ;* parses the args
myshades()      ;* defines colors

> cat myshades.gsf
function myshades()
'set rgb 16  90   0   0'   ;* map color
'set rgb 17 100 100 100'   ;* dark grey
'set rgb 18 200 200 200'   ;* light grey

> cat parseargs.gsf
function parseargs(args)
while (1)
  _arg.a=subwrd(args,a)
  if (_arg.a=''); break; endif
  a=a+1
endwhile
_nargs=a-1



It is so much easier to explain by showing an example.

Since I have a function that reads command line arguments apparently that has to be the very first thing in the file or grads hangs. In other words it can't be in the "master" file, even if that's the first thing, on the first line, that grads does. The actual function that handles the command line argument needs to be the first thing (seemingly) in the actual grads script.
