REXX/CICS supports (by support for CICS LINK and CICS XCTL
REXX/CICS commands) the ability to invoke CICS programs written in
any REXX/CICS supported language.
It likewise provides the same
support for the programs used to implement new REXX commands,
which are defined by using the DEFCMD and DEFSCMD commands.
Support is
also provided to allow an EXEC CICS START to be issued from REXX execs.
The full range of DBCS functions and handling techniques that
are included in SAA Level 2 REXX are available to the REXX/CICS
user.
- A TERMID command has been provided to return the four
character terminal identifier of a CICS user.
- A retrieve PF key may be specified to retrieve the last
input line entered using line-mode I/O
while in the REXXTRY interactive utility
(CICRXTRY exec).
Refer to the SET RETRIEVE command.
- The SET TERMOUT command allows line-mode terminal output (from
SAY or TRACE) to be directed to a CICS temporary storage queue instead
of, or in addition to, the terminal.
- The PULL instruction sets the REXX variable PULLKEY, with the
name of the AID key pressed if PULL read data from the terminal.
- Line-mode output to the terminal causes MORE to
appear in the lower right hand corner of the screen, when the screen
is full.
Press Clear or Enter to proceed.
- Line-mode input from the terminal causes READ to
appear in the lower right hand corner of the screen.
