Developing Assembler language applications
Use this information to help you code assembler language programs that you want to use as CICS application programs.
Working storage
Working storage for assembler language programs is allocated either above or below the 16 MB line, according to the value of the DATALOCATION parameter on the PROGRAM definition in the CSD.Sample programs
A set of sample application programs is provided to show how EXEC CICS commands can be used in a program written in assembler language. These programs are AMODE(64) and use relative addressing, except for DFH$AREP. DFH$AREP uses relative addressing but is AMODE(31) because it demonstrates the use of the HANDLE CONDITION LABEL command.| Sample program | Map set | Map source | Transaction ID |
|---|---|---|---|
| DFH$AMNU Operator instruction (3270) | DFH$AGA | DFH$AMA | AMNU |
| DFH$AALL Update (3270) | DFH$AGB | DFH$AMB | AADD, AINQ, AUPD |
| DFH$ABRW Browse (3270) | DFH$AGC | DFH$AMC | ABRW |
| DFH$AREN Order entry (3270) | DFH$AGK | DFH$AMK | AORD |
| DFH$ACOM Order entry queue print (3270) | DFH$AGL | DFH$AML | AORQ |
| DFH$AREP Report (3270) | DFH$AGD | DFH$AMD | AREP |
The transaction and program definitions are provided in
group DFH$AFLA in the CSD and can be installed using the following
command:
CEDA INSTALL GROUP(DFH$AFLA)
The
following record description files are provided:
- DFH$AFIL: FILEA record descriptor
- DFH$AL86: L860 record descriptor
