The following options are used only in INFILE statements
that involve VTOC (Volume Table of Contents) access:
- CCHHR=variable
-
defines a SAS character
variable of length 5 whose value is set to the CCHHR of the last VTOC
record that was read by SAS. The returned value is in hexadecimal
format; it can be printed by using the $HEX10. SAS format.
- CVAF
-
tells SAS to use the
Common VTOC Access Facility (CVAF) of the IBM program product Data
Facility/Device Support (DF/DS) for indexed VTOCs. If the VTOC is
not indexed, or if your installation does not have CVAF, this option
is ignored.
Note: When you use CVAF and CCHHR=,
values that are returned for Format-5 DSCB records are not valid,
because indexed VTOCs do not have Format-5 DSCB records.
