The parameter list that CICS® VT passes to an FBE is different to an IRD.
For MULTFBE, the linkage section is:
01 VSAM-FIELD PIC X(233).
01 DB2-FIELD PIC X(1) .
COPY VIDFBEC .
COPY APPLCTL .
01 DB2-RECORD-KEY .
02 DB2-OBJECT-ID PIC X(6) .
02 DB2-REC-TYPE PIC X(3) .
02 DB2-USER-ID PIC X(8) .
In the mapping shown in Figure 1, MULTFBE is mapped against the field called FILLER, which is 233 bytes. This field is not mapped to a DB2® column. The second parameter which CICS VT passes to an FBE is the address of the DB2 column. Because no column is mapped to FILLER, no address is passed and the linkage section field DB2-FIELD is a placeholder.
