Hi Geoffrey,

I hadn't come across this feature before and you're right about it not being well documented. However, what it appears to do is return to the topmost program in the call stack. Eg, three small PRG's :

Test1.PRG
? "In test1"
Do Test2
? "Still in test1"

Test2.PRG
? "In test2"
Do Test3
? "Still in test2"

Test3.PRG
? "In test3"
Return to Master
? "Still in test3"

Issuing a DO Test1 will give you 4 lines of text
In test1
In test2
In test3
Still in test1

Any clearer?

HTH

>This is not a well documented feature, but I am trying to track what happens when this statement is used. Just where does it return? How can you tell what line of code will be executed next? It would seem desirable to have a statement like 'set master', and know that is where you end up if you make the call.
