re: two command buttons launch two sub-routines

As Ed mentioned, recoordinating two RUNning processes would be difficult.

If these buttons launch routines that can run without user intervention and then terminate (ie: gather/report function) Or if the buttons are spawning completely self-contained programs (It would appear to be an MDI not contained in the parent window) You could easily use run.

Button1.click: !/N2 Sub1.exe **gathers data1 & spools report
Button2.click: !/N2 Sub2.exe **gathers data2 & spools report

(/N2 = nowait active and minimized, see "HELP RUN")
