Difference between Exit(1) and Exit(0)?

Asked by: 24220 views PeopleCode

In an App Engine PeopleCode, it’s not uncommon to see code that works on the following logic.
You have a condition and if it’s TRUE, you want Exit(1) to execute.
If the condition is FALSE, you would like Exit(0) to execute.
Depending on the way in which you have designed the App Engine, this can completely change its flow.

Can you explain what is the difference between Exit(1) and Exit(0)?

    This is my understanding –
    Any non-zero return code is some kind of error. The way it will be handled depends on “On Return” value for each step of application engine.

    So exit(0) – is success

    exit(1) and On Return = Abort – is error and exit program immediately
    exit(1) and On Return = Break – is exit current step and section
    exit(1) and On Return = Skip Step – exits current step, continue with next step
