Hi,

what exactly want you do, start another program from your own program
and catching its output, or simply start your program and write the
output to a file?

(I assume that you use widows as you mentioned AdaGide which is a
windows tool)

The later can be done by simply redirecting output as under Unix via ">"
(tested with NT 4.0)
e.g. MY_PROG > file.out 2> file.err

The first one can be done with anonymous pipes. For an example, download
the AdaGide sources and have a look into package body "RunChoices.adb".
Procedure "StartTheProcess" for the start with pipes and function
"ReadFromPipe" for how to get the result.
