Is it possible to run one program to start or select a process for instance, and then link to a second program to perform a task based on the results of the first program.
I remember doing this in BBC BASIC years ago and found it useful when writing long, involved programs.
Sorry but I don't understand. Do you want to open the Devlopment environment with a certain source file in it or do you want to run a compiled B4PPC app and pass a string to it. If the latter then yes.
