Changing File Characteristics<br />

FIVSAM, NOFIVSAM<br />

IGNore<br />

Specifies whether <strong>CA</strong> <strong>Dynam</strong>/FI is allowed to convert the file to a VSAM file if a<br />

VSAM DLBL record is found. This parameter overrides the default set in the<br />

DYNAM/FI option record. (Note that if FIVSAM is specified, <strong>CA</strong> <strong>Dynam</strong>/FI,<br />

rather than VSAM/SAM, per<strong>for</strong>ms the modification from SD to VSAM by<br />

creating ACB/RPL.)<br />

Signals that ignore processing is in effect. The file is not opened. For input, an<br />

EOF (end-of-file record) will be returned at the first GET/READ. For output, all<br />

PUTs/WRITEs will be discarded.<br />

<strong>CA</strong> <strong>Dynam</strong>/FI IGNORE processing is an alternative to the IBM 'ASSGN IGN'<br />

facility. If, in normal processing, the logical unit derived by DYNAM/FI is<br />

assigned 'IGN', but the DLBL has the <strong>CA</strong> <strong>Dynam</strong>/FI 'IGN' option, <strong>CA</strong> <strong>Dynam</strong>/FI<br />

processing will prevail; i.e, the IBM facility will be ignored.<br />

This option is not supported <strong>for</strong> DTFDA (VCKD) or <strong>for</strong> <strong>CA</strong> SORT input/output<br />

files.<br />

LRECL=nnnnn<br />

Defines the logical record length <strong>for</strong> the file.<br />

Default: Record length defined in the Catalog or else record length in the<br />

user's program.<br />

MAXCI=nnnnn<br />

Specifies the maximum CI size to be used <strong>for</strong> FBA devices to calculate a new<br />

CISIZE with BLKSZ=OPT. When BLKSZ=OPT and the device pointed to is FBA,<br />

the block size is not changed but the DTF CISIZE field gets a computed value<br />

based on MAXCI parameters. nnnnn must be a valid FBA CI size or zero. If this<br />

operand is specified but the device pointed to is not FBA, it will be ignored.<br />

Default: Control interval size specified at installation.<br />

NOFI<br />

NOTAPE<br />

RECFM=xx<br />

Ignores <strong>CA</strong> <strong>Dynam</strong>/FI processing <strong>for</strong> this file (used with programs such as<br />

DITTO, which modifies its DTF after OPEN processing is complete).<br />

Prevents the operator from switching to TAPE <strong>for</strong> this generation of the disk<br />

file. Overrides the Catalog specification of FI <strong>for</strong> this data set.<br />

Specifies the record <strong>for</strong>mat <strong>for</strong> the file. Record <strong>for</strong>mats supported are:<br />

F<br />

FB<br />

V<br />

VB<br />

U<br />

Fixed<br />

Fixed-blocked<br />

Variable<br />

Variable-blocked<br />

Undefined<br />

Default: Record <strong>for</strong>mat in the Catalog or else <strong>for</strong>mat remains unmodified.<br />
