Message processing with IMS TM
IMS Transaction Manager application programs can be written in assembler language, C language, COBOL, Pascal, and PL/I to process messages.
IMS Spool API
The IMS Spool API support provides feedback to the application program when IMS detects errors in the print data set options of the
CHNG
and
SETO
calls.
IMS Message Format Service
The IMS Message Format Service (MFS) is a facility of the IMS Transaction Manager environment that formats messages to and from terminal devices, so that IMS application programs do not deal with device-specific characteristics in input or output messages.
Callout requests for services or data
IMS applications can issue callout requests for services or data, and optionally receive responses back in the same or a different transaction, through IMS Connect and OTMA. The request for services or data is a
