PARAML
Sets parameters from a data block
Option P1 = ‘NAME’
Return the name and purge status of a data block.
Format:
PARAML /DBNAME/'NAME'////S,N,NODB//S,N,NAME $
Input Data Block:
None.
Output Data Block:
DBNAME Any data block.
Parameters:
NODB Output-integer. Set to -1 if the data block is purged.
NAME Output-character. Name of the data block. Set to blank if data block is
purged.
Remarks:
1. This option is useful for checking to see if the data block is purged on the CALL
statement(s) in the calling subDMAP(s).
2. If DBNAME is specified on the SUBDMAP statement, then NAME is the name
appearing on the corresponding CALL statement. This process is repeated until
the DBNAME no longer appears on a SUBDMAP statement.
Example:
Check the name and purge status of the MAA matrix.
PARAML /MAA/'NAME'////S,N,NOMAA//S,N,MAANAM $
