GDDM V3R2 General Information
GC33-0866-03

GDDM function can be invoked by application programs that use standard OS/370 call interfaces. These include application programs written using the programming languages and compilers shown in Table 7.


Table 7. Programming languages and compilers
Language	Compiler / Interpreter	Notes
Assembler	H Assembler or High Level Assembler
APL2		1, 2, 3
BASIC	IBM BASIC	1, 2, 4
COBOL	DOS/VSE OS/VS VS COBOL II
C	C/C++ Compiler
C/370	C/370 Compiler	1
FORTRAN	VS FORTRAN	1, 5
PL/I	DOS Optimizing Compiler OS Optimizing Compiler Checkout Compiler
REXX	TSO/E 2.1.0	1, 6

Notes:

1. GDDM Interactive Map Definition (GDDM-IMD) does not generate application data structures in FORTRAN, IBM BASIC, APL2, C/370, or REXX. However, application data structures generated by GDDM-IMD can be converted for use in C/370 and REXX applications. Also, mapping techniques can be used in FORTRAN and IBM BASIC applications for which programmers create their own data structures.

2. High-performance alphanumerics is not supported in BASIC and APL2 applications.

3. The GDDM auxiliary processor (AP126) gives full-screen control and allows access by APL programs to the functional capabilities of GDDM Base and GDDM-PGF.

4. IBM BASIC/VM and IBM BASIC/MVS each provide a CALL statement that can be used to call GDDM.

5. GDDM application programs written in FORTRAN cannot run under the CICS and IMS subsystems.

6. GDDM-REXX is supported in the VM and MVS environments. There is no support for GDDM-REXX in the VSE environment. In the MVS environment, TSO/E 2.1.0 is required. The GDDM-REXX component of GDDM 3.2 must be both licensed and enabled.
