Hi,

How do we check the file status code in Assembler???
I mean, if I open a file, then in COBOL we check if the open was sucessful using file status code, which we mention in SELECT clause.

How do we do that in Assembler??? how do I check if my file operation was sucessful???

Thanks for all the info you can provide.

Hi !

Example:

OPEN IN01(INPUT)
LTR R15,R15 ...CODE IN R15
BZ DoSomeThing ...R15 = Zero = Ok

... ... ...

CLOSE IN01
LTR R15,R15 ...CODE IN R15
BZ StopRun ...R15 = Zero = Ok ...R15 = NULL IST OK

Cause you are using IBM-Systemmacros. These macros or programmse alle apply to the standard IBM Register conventions.
