The first time MULTIRD is tested is when you run VIDLOAD. Because multiple output records are written for each VSAM record, you must specify the DD statement LOADOUTM in the VIDLOAD JCL.
Figure 1 shows the JCL for migrating APPLCTL.
//jobcard
//*
//VIDLOAD EXEC PGM=VIDLOAD,PARM='APPLCTL',REGION=8M
//STEPLIB DD DISP=SHR,DSN=appl.DRIVERS.LOAD
// DD DISP=SHR,DSN=VID.SVIDLODE
//SYSPRINT DD SYSOUT=*
//LOADIN DD DISP=SHR,DSN=your.VSAM.UNLOAD
//LOADOUTM DD DSN=your.APPLCTL.LOADDB2,
// DISP=(,CATLG,DELETE),
// UNIT=SYSDA,SPACE=(CYL,(150,35),RLSE),
// RECFM=FB,LRECL=242,
The record length of the output file is 242. This is the length of the longest DB2® row plus 2 bytes. This is explained next.
