File opening error in PL/1

In Pl/1 while opening the file i might get various file errors. How to handle those errors
For Ex: In COBOL if i handle file status not equal to zero then we can identify there is an error occured while opening. How to identify the same in PL/1?

We have the same error for READ,WRITE,LOCATE(SET) also.How to handle?

using ON.

You have something like ON ERROR, ON CODE etc... you can use them for file handling

Thanks for your replay.

But,ON CODE,ON SIZE ERROR, .. these are all done in COBOL.

I want to solve the problem in PL/1.Could you help me to solve it?

ponkala: ON is a PL/I construct. Read the Language Reference manual from the link at the top of the page and you'll find the ON units in PL/I refer in turn to an entire chapter on the different conditionals that can be intercepted -- ENDFILE, CONVERSION, KEY, SIZE being among them.
