DEPEN
Specifies the dependence of a data block or parameter
DEPEN Specifies the dependence of a data block or parameter
Specifies the dependence of a data block or parameter on another data block,
parameter, or virtual parameter.
Format:
DEPEN
Meaning: dep_* is dependent upon indep_*. In other words, if any or all of
indep_* changes, or is also marked for deletion. The RESTART module
detects changes and marks dep_* for deletion.
Variables:
⎧dep_db_name( DB)
⎫ ⎧indep_db_namei( DB)
⎫

⎨dep_param_name( P)

dep_* Dependent data block, parameter, or virtual parameter as indicated by
DB, P, or VP, respectively.
indep_* Independent data block, parameter, or virtual parameter as indicated by
DB, P, or VP, respectively.
desc_loc Description locator of the independent record, entry, or item and the
format is
[ record_name]
[ : [ entry_name]
] [ : [ item_name]
]
Remarks:
1. des_loc is specified in order to isolate the independent data. In other words, the
dependency is limited to a specific record, entry, and/or item. For example,
DEPEN A/B $ delete A if any item in B changes
DEPEN A/B:C $ delete A only if record C changes
DEPEN A/B:C:D $ delete A only if entry D of record C
changes
DEPEN A/B:C:D:E $ delete A only if item E in entry D
of record C changes
2. If record_name, entry_name or item_name is not defined in the DATABLK
description, then leave these fields blank but specify the colon.
