The QMF EXEC library contains fixed-length records. It can be concatenated only to other exec libraries that have fixed-length records. If the library contains variable-length records, you must create a copy of the QMF library with variable-length records.
Later in the install, you will allocate the QMF exec library (QMF720.SDSQEXCE.VB) as a SYSEXEC data set by concantenating the library to other exec libraries.
In the following JCL (from DSQ1EINV), the library QMF720.SDSQEXCE is concatenated to an exec library named SYS2.EXEC:
//SYSEXEC DD DSN=SYS2.EXEC,DISP=SHR // DD DSN=QMF720.SDSQEXCE,DISP=SHR
Change the serial number of the volume for the copy of the library.
//DSQTEVB.SYSUT2 DD DISP=(NEW,CATLG),UNIT=SYSDA,
// SPACE=(8800,(400,50,25)),VOL=SER=XXXXXX,
// DCB=(RECFM=VB,LRECL=84,BLKSIZE=8800)
//DSQ1EJVE JOB (ACCT),NAME, // CLASS=A,MSGCLASS=A,MSGLEVEL=(1,1), // USER=Q,PASSWORD=Q
//DSQTEVB PROC RGN='2048K',
// QMFTPRE='QMF720 ', Prefix for QMF libraries
// CLIST= Leave blank;

If the job fails, correct the error and rerun the job.
