Application programming for IMS TM
IMS™ provides support for writing application programs to access IMS transactions.
- Defining application program elements for IMS TM
You can write application programs to communicate with the IMS Transaction Manager using DL/I calls in assembler language, C, COBOL, Java™, Pascal, or PL/I. - 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 callout request.
