| The link between the transaction and the program is defined in the Stage 1 definition (See the IMS Installation Guide Volume II, APPLCTN and TRANSACT Macros). The link between the format (MFS) and the transaction is defined in the MID - look for "MSG TYPE=INPUT" - the transaction code is the first MFLD entry (See IMS Application Programming - Transaction Manager). |

Hi Bithead,
Thanks for the reply.
I am still not able to find the link between the PSB and program. Since the following code only connects a PSB and transaction name. How is program name derived from PSB.
APPLCTN PSB=DFSIVP1,PGMTYPE=TP
TRANSACT CODE=IVTNO,MODE=SNGL,
MSGTYPE=(SNGLSEG,NONRESPONSE,1) |

The PSBGEN macro for this PSB in ADFSISRC(DFSIVP1) is
PSBGEN LANG=ASSEM,PSBNAME=DFSIVP1
In an MPP environment, the PSB name must match the program name - see IMS Utilities Reference: System - Chapter 2. |
