I am using a Sequential file for OUTPUT in assembler code. For this I am using PUT to write data to output. But after using PUT how can I check the return code whether PUT was successful or not.

Somewhere I heard that we can use
LTR r15,r15. If r15 is zero it will be ok. But when I debuged the program it is giving some address in R15 and also PUT is successful. I don't know whether we can use R15 or not.

There is also one option SYNAD in DCB for error routines. Can anybody tell me how we can check the return code after PUT.

Hi k_sharma,

I don't know, if the SYNAD disturbs the normal error-checking,
but I do it always that style :

To check a PUT Statement on errors do the following :

Testing R15 after a put is useless. To be honest, I wouldn't worry about it too much. If the put is in error your program will abend. You could write a SYNAD exit, but I never bother.
