SKRxxxx

The SKRxxxx system initialization parameter specifies that a single-keystroke-retrieval operation is required.

SKRxxxx='page-retrieval-command'
Start of change'xxxx' specifies a key on the 3270 keyboard which, during a page retrieval session, is to be used to represent a page retrieval command. The valid keys you can specify as a system initialization parameter or as an override are PA1 through PA3, and PF1 through PF24.  Therefore it is possible to specify up to 27 keys in total. End of change

The 'page-retrieval-command' value represents any valid page retrieval command, and must be enclosed in apostrophes. It is concatenated to the character string coded in the PGRET parameter. The combined length must not exceed 16 characters.

Note: If full function BMS is used, all PA keys and PF keys are interpreted for page retrieval commands, even if some of these keys are not defined.
