COMPILES is an MVS utility program to automate and speed up the
compilation of large numbers of programs. COMPILES can achieve
throughputs of 500 to 5000 compilations per hour, including HLLPI
translation and link-edit.
This tool is very handy in a z/OS V2R1 migration when a large number of
recompilations are necessary in an Enterprise COBOL for z/OS V5.1
migration.
At the center of COMPILES is a powerful program shell which
replaces the JCL procedures and TSO CLISTs typically used to compile
programs. Based on language definitions contained in the Process
Table, the COMPILES shell invokes standard HLLPI translators,
the assembler, compilers, pre-linkers and the linkage editor, as required
for proper compilation of each program. Regardless of the number of
programs processed, COMPILES runs as a single job step with minimal
impact on the system.
COMPILES's main benefits are:
Time and Resource requirements reduced by 75% - COMPILES uses
a minimal amount of JCL, pre-allocated data-sets and several I/O
reduction features to achieve dramatic savings in elapsed time and
overall consumption of system resources.
Check-out time reduced by 90% - COMPILES provides
consolidated error listings: the user knows at a glance what
compilations failed and why; restarting failed compilations is
automatic.
Flexible customisation capabilities to support most of the IBM and
non-IBM languages.
COMPATIBILITY
COMPILES executes on any MVS/ESA, OS/390 or z/OS system, and currently
supports the following environments:
Assembler H and High-Level Assembler
VS COBOL for OS/VS
VS COBOL II, COBOL for OS/390 and VM, Enterprise COBOL
Report-writer Pre-compiler
PL/I Optimizer, Enterprise PL/I for z/OS
Fortran
OS/VS RPG II (including Auto-Report)
CICS (Programs and Maps)
IMS/DB & IMS/DC
DB2
Datacom SQL & DLM
IDMS DML
Metacobol
Easytrieve Plus
Dylakor 260 & 280
Abend-AID
Xpediter
Other environments will be supported in the future.
TABLES
COMPILES's processing is driven by two tables.
The MODULE table identifies each application program and sub-program,
along with its language, type (main/sub), HLLPI requirements and other
options. In the Prism-CS
environment, this table is built automatically by the Inventory
Validation program.
The PROCESS table, which defines which compilers, HLLPI translators, and
other processes must be executed to properly compile and link-edit the
corresponding modules. The PROCESS table must be customised at installation
time using the sample table provided in the COMPILES installation
library.
OUTPUT
Program compilation under COMPILES produces different types of output:
Control report and statistics
Compilation error messages (SYSTERM) written to SYSOUT
Load-modules, object modules, symbolic maps, DBRM, are created as
specified in the Process Table
Listings for failed compilations are written to PDS members
Listings for successful compilations can be written to SYSOUT and/or
written to PDS members, optionally in ISPF packed format
At the end of its processing, COMPILES optionally issues TSO SEND
commands to notify the user of a pre-determined number of compilation failures
