All of TPF's online and general files must be properly formatted before they are loaded with programs and data records. The disk formatter (FMTR) runs under the control of MVS and is used to format a disk pack for use in the TPF system.
SIP Stage II will create the JCL to format the required loader general file.
With ISO-C support, SIP splits the L1A2E job into L1A2E and L1A3E during Stage II. In this case, you need to modify your JCL. Following is a sample of the JCL produced by SIP.
//L1A2E EXEC PGM=FMTR40,REGION=8192K //STEPLIB DD DSN=ACP.LINK.REL40.BSS,DISP=SHR //DUMMY DD DUMMY //SYSPRINT DD SYSOUT=A //SYSUDUMP DD SYSOUT=A //FMTDD2 DD SYSOUT=A //FMTSNP DD SYSOUT=A //FMTDD3 DD DSN=GNFLBSS,UNIT=3380, // VOL=(PRIVATE,,,,SER=SA0999), // DISP=(NEW,KEEP),SPACE=(ABSTR,(1,1)) //FMTDD1 DD * FMT L N 0000001 0000001 338L FMT END /* //L1A3E EXEC PGM=FMTR40,REGION=8192K //STEPLIB DD DSN=ACP.LINK.REL40.BSS,DISP=SHR //DUMMY DD DUMMY //SYSPRINT DD SYSOUT=A //SYSUDUMP DD SYSOUT=A //FMTDD2 DD SYSOUT=A //FMTSNP DD SYSOUT=A //FMTDD3 DD DSN=GNF2BSS,UNIT=3380, // VOL=(PRIVATE,,,,SER=SA0999), // DISP=(NEW,KEEP),SPACE=(ABSTR,(522,2)) //FMTDD1 DD * FMT 4 N 0000002 0003413 3380 FMT END /*
Stage II will only create and list the required MVS Job Control Language (JCL) and input to initialize and format the first module of each device type for the online files. It is up to the user to actually run these MVS jobs. It will also be necessary to modify the VOLSER= parameter of the JCL for modules other than the first module of each device type. The output of SIP is placed into PDS member FMTRDECK of the source library for access by the user.
