Hi,
I have a quick question on the below code with how the PERFORM statement works..
| Code: |
.
.
.
PERFORM PARA-NAME-1 THRU PARA-NAME-1.
.
.
.
PARA-NAME-1.
.
.
.
EX-PARA-NAME-1.
EXIT. |
Ideally the above PERFORM statement should have been written as
PERFORM PARA-NAME-1 THRU EX-PARA-NAME-1. But there was a typo mistake and the actual code was PERFORM PARA-NAME-1 THRU PARA-NAME-1. When the above code is executed will the statements inside the PARA-NAME-1 would be executed or not? |

They will be executed (once). |

If there is an instruction in PARA-NAME-1 that issues a GO TO EX-PARA-NAME-1, the result will be unpredictable as the execution can "fall thru" and cause a wide variety of surprises. . . |

| Why not run a quick test for what you've asked? |
