Hello,

I have a job (job1) that creates a file which contains a 4 digit code. I also have a second job (job2) that will take the file created in job1 as input. Whether or not steps in job2 will be executed will depend on the 4 digit code in the file. Can somebody please give me an idea on how to accomplish this?

Ex. File from job1 has 0000, step1 in job2 will be executed.

Thanks!

Use DFSORT/ICETOOL
1) filter data selecting the record containing the code, output to a temporary dataset.
2) test for the temporary dataset being empty, setting return code accordingly. ICETOOL COUNTS function as I recall.
3) submit job2 from job1 if return code indicates code was found.

Method 1. Use DFSORT/ICETOOL/SYNCSORT

Filter-out records with required "code" into separate file. Use parameter(s) like NULLOFL=RC4 to indicate the presence of required "code" in the input file. Use RC from SORT step in JCL "// IF (SORTSTEP.RC EQ 0) THEN " - to execute, or to skip the //STEP1, or whatever.

Method 2. Use IEBCOMPR, or SUPERC, or any other Compare utility

Compare your "code file" with constant file, like this one:
Quote:
//CONST DD *
0000
All compare utilities I know return different RC in case the compared files are equal, or not. Next, use the same "// IF " as in Method 1 above.

Other methods can be easily invented using other available tools.
