PGRET

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.
  1. 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.
  2. In pseudoconversational mode, each character string is unique with respect to the leading characters of any terminal input message.
  3. 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: ( ) ' =

  4. 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.
  5. 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.
