[SOLVED] Using Variable as a LABEL value in loop ((FOC305) SPECIFIED LABEL NOT FOUND)

Hi

I'm trying to put a variable value as a LABEL name which is being used in a loop. Somehow I'm getting the error : "(FOC305) SPECIFIED LABEL NOT FOUND". &cnt is assigned before this piece of code executes. All works fine until the loop needs to break out on the count of 9.

 
-SET &LOOP_VAR='LOOP2' || &cnt;
-TYPE &LOOP_VAR
-REPEAT :_&LOOP_VAR.EVAL WHILE &I LT 9;
-* ======================================================================
-* do something
-* =======================================================================
-:_&LOOP_VAR.EVAL

You cannot do that; and you have no need to. Make the label a simple constant, both in the target line and in the earlier reference within the GOTO or REPEAT directive. &I varies; the label does not.

I understand that this is not required in normal day scenario. My specific requirement bounds me to include a common module multiple times in the same report code. This loop is present in the common module.
Now, when this loop is called the second time, same label name is causing name conflict. Hence, the usage of "&cnt".

Pradhan,
I tried your idea without using a variable for the loop. Here are 2 fexes: LCALL and LVAR.
  
-SET &ECHO=ALL;
-*LCALL
-SET &K=1;
-INCLUDE LVAR
-SET &K=2;
-INCLUDE LVAR


  
-*LVAR
-REPEAT #LOOP_VAR FOR &I FROM 1 TO &K;
-* ======================
-TYPE do something
-* =======================
-#LOOP_VAR

This works for me.
My assumption is that either:
1. as long as you branch forward you can have identical labels
2. labels are local to the included fex

That's certainly true for -GOTO

-- the target label of a GOTO in an -INCLUDE MUST be in the same file; and then the same file can be included multiple times. Just have to make sure the label does not conflict with those that appear in the enclosing file.

Same should apply to -REPEAT.

Danny and J,

I agree that holds for GOTO. But somehow I find that including the same fex multiple times in a blank test file doesn't run into problems.
It probably halts when the label name conflicts with labels in other included fex. Still a gray area why it's happening. Meanwhile, I've just updated the name of the label in the included file to something ridiculous which might not be used anywhere else...

Thanks for your response though!
