CA Dynam for VSE User Guide

Chapter 8: Maintaining the
Catalog−DYNCAT Program
The DYNCAT utility program is used to create, maintain, and report upon the
Catalogs used by the CA Dynam system. These include the CA Dynam dataset
Catalog (CAICATL) and the VTOC index Catalogs, if indexed VTOC support is
being used. DYNCAT is provided with the combined CA Dynam system and
with any of its subset systems.
You request DYNCAT functions by submitting DYNCAT control statements. For
VSE users, these will be accepted from the SYSLOG device if the program is
executed from the console; or, if the program is executed from a job stream,
the control statements will be read from the SYSIPT device.
SYSIPT may be assigned to a card reader, magnetic tape unit, or DASD, and
must consist of 80-byte records. (For MVS users, the control statements will
be accepted from the operator console if the program is executed with
SYSPARM=CONSOLE, or they may be submitted from either SYSIN or any
sequential or partitioned dataset.)
Output is usually directed to the printer. However, you can use CA Dynam/FI
unit record simulation to direct the output file to disk, as in the example
below.
// DLBL FISYSLS,'OUTPUT.FILE',7,SD,,SYS008
// EXTENT SYS008,SCRTCH,1,0,256,10
// ASSGN SYS008,DISK,VOL=SCRTCH,SHR
// EXEC DYNCAT,SIZE=128K
.
.
Output to disk is not available without CA Dynam/FI because CA Dynam's
reporting format allows 133 characters, while IBM's DTFDI supports only 121
characters.
