EG 5.1 conditioning the running of programs on previous programs running with return code 0 or 1

[JamesNewcombe]

Hello

Is there a simple way to run a program in EG on the condition that previous, depended-upon, programs have run successfully? That is, if the return codes from all previous programs are 0 (or 1) then the next program can run.

Hope that makes sense.

Thanks

James
