The PGRET system
initialization parameter specifies the character string that is recognized
by terminal control as a BMS terminal page-retrieval command.
- PGRET=character(s)
- The character string can be 1 through 7 characters.
- Each character string is unique with respect to the
leading characters of every other transaction identification defined
in the CSD. A command requested by a single character precludes the
use of all other transaction identifications starting with this character.
- In pseudoconversational mode, each character string is unique
with respect to the leading characters of any terminal input message.
- A field-separator or other suitable delimiter may be specified
in each character string to separate this command code from the remainder
of the paging command when entered by an operator. For example:
PGCHAIN = X/
PGCOPY = C/
PGPURGE = T/
PGRET = P/
This reduces the risk of creating a nonunique
command. (See Note 1.)
Restrictions If you specify PGCHAIN,
PGCOPY, PGPURGE, or PGRET in the SIT, the characters you choose must
not include any of the following: ( ) '
If you specify PGCHAIN,
PGCOPY, PGPURGE, or PGRET as a PARM, SYSIN, or console parameter,
do not enclose the characters in quotation marks. The characters you
choose must not include an embedded blank or any of the following:
( ) ' =
- PGCHAIN, PGCOPY, PGPURGE, and PGRET are required only if full
function BMS is being used. For information about the BMS page retrieval
transaction CSPG, see CSPG - page retrieval.
- CICS always processes a paging command entered by the operator
before initiating a transaction invoked by an EXEC CICS RETURN command
with the TRANSID option.
