Hello,
I have a source library for PLI programs which has 'NUMBER off' profile. However I see sequence numbers [ from col 72 to 80]. Due to the number of changes to done to programs & NUm OFF profile, those sequence numbers are out of sequece.
Does this effect the execution flow of program.
If Num Off is in profile, Do I need to clear the content of col 72 to col80.


Appreciate If any one can explain how compiler/interpreter will consider these sequence numbers.

I did not get any compiler errors. My testing also went on fine, however I want to confirm that this will not cause any abnormal behaviour in production.

There was a differenct situation , where i left some characters in sequence area & program is behaving abnormally sometimes in production. example is below[ */ is in column 73]:


--+----5----+----6----+----7----+--

*/

Will compiler/interpreter takes the character present after col72 into consideration?

Appreciate the clarification

Curiosity: have you checked the PL/I Programming Guide, compiler option MARGINS, to see what it says? How does that compare to how your compiler options are set?

I recommend you move any non-sequence number characters to the 1-72 column range. Then either remove all sequence numbers or turn NUMS ON.

Why continue to worry if there is some unforeseen consequences when you can easily fix it?

I have looked in manual for MARGINs options. It helped me.

However I saw one more compiler option used SEQUENCE(73,80). I don't see anything about this option in manual which I found on ibmmainframes.com.

Pedro & Robert thanks for your valuable feedback.
