This information is from the QMF V3R1 Reference Manual (SC26-4716).
For IBM JCL to create QMF data with DXT, please have your Tandem analyst contact
the Data Build Product Manager.
Note that IXF data is in variable length format. Data Build supports variable length
records only from tape input; variable length records cannot be copied to disk for
input to Data Build.
Creating Data from VSAM The following JCL example copies records from a VSAM data set to a sequential data
set. In this example, the VSAM data set was defined with variable length records,
RECORDSIZE(46 80). If the VSAM data set is defined with variable length records, the
sequential output data set must be variable length with an LRECL at least as large as
the maximum VSAM record plus 4.
The VSAM data set name is specified in INDATASET; the output dataset name is
VARIABLE on the DD card with ddname OUTPUT as referenced in the REPRO
statement OUTFILE parameter.
