CHECK
Statements
Use TSIDASS CHECK to determine if a specific version of a dataset
exists in the BIM-EPIC Catalog, or if a particular "Start Track 1" dataset
exits.
Syntax The following is an example of an RSTRT statement syntax.
CHECK dtfname
Parameter Required? Valid Default
dtfname Yes 1 to 7 characters None
SYSxxx Yes 000-254 None
Specify one of the following two (required):
INPUT No None None
OUTPUT No None None
EXT No 1 to 255 1
Parameter Definition
dtfname Identifies the dataset to be opened. Use the DTF
name or DD name as it appears on the label
statement.
SYSxxx Specifies the logical unit to assign. It must be the
same logical unit number that was in use when the
checkpoint was taken.
INPUT Specifies that the dataset was last opened as input.
OUTPUT Specifies that the dataset was last opened as output.
EXT Specifies the sequence number of the extent to be
re-opened. This is necessary only for disk datasets
and only if the dataset is to be opened at an extent
other than the primary extent. This number will be
equal to the number of BIM-EPIC EP053 messages
that were issued for the dataset prior to the
checkpoint from which the program will be
restarted.
