JCL skeleton?
well, there might be a problem with what your system knows SAS as (SAS,
SAS8, SAS6, SASTST, whatevertheheck). Here is a sample, but this can vary
a lot
//jobname JOB stuff
//STEP1 EXEC SAS
//MYDATA DD DSN=MY.DATA.FILE,DISP=SHR
//SYSIN DD *
data test ;
infile mydata ;
input ....
JCL is _never_ in lower case. "stepnames" (jobname, stepname, ddname) are
8 (max) alphanumeric chars, begin with alpha. Don't let your JCL get past
col 70 (ok, 71) or it will be seen as 'continued' on the next line.
usually only a dd-stmt will be continued and it is easiest to break at a
natural place: where there is a comma:
//NEWFILE DD DSN=NEW,FILE,DISP=(NEW,CATLG,DELETE),
// UNIT=SYSDA,SPACE=(TRK,5,2)),
// DCB=(LRECL=80,BLKSIZE=8000,RECFM=FB)
Use the minimum JCL you need. A dataset is NEW only once. if you are
writing one, don't leave the complete jcl above in your code on a second
run. You can comment out lines 1 and 2 ("//* "), and change the
"disp" to "DISP=SHR ,CATLG,DELETE)," -- I just overtyped the "(NEW" ...
JCL stops on the line when it encounters a blank...never sees the rest.
be careful writing to a PDS that you NOT include DCB info as the info on
the JCL overrides anything stored on the disk or tape. if you use
incorrect DCB info, you will overwrite the "DSCB" and the file may be
unusable.
Gary DeWard Brown has a _very_ handy book on JCL. look for it or go to
Amazon and order it. Good luck, and hth --Joe
