Compiler
The ULTIM
compiler
allows all the applications to immediately benefit from a
substantial
reduction in the CPU time used, without any change in the JCL or in
the coding of the existing applications.
It
allows you to choose between 3 processing modes:
- Interpretive mode
- validation of the program and
execution of the generated control blocks
- Compile-and-go
mode
- validation of the program,
compilation in memory and immediate execution
of the code
- True compiler mode
- validation,
compilation and production of a module unlimitedly
reusable without the original source
program
Advantages
of the interpretive mode
- Performs the most elaborate
data validity checks
- Recovers from the maximum
number of error conditions
- Mainly useful during the
initial development steps or to process low-volume data
-
Advantages
of the compile-and-go mode
- Tests have shown a
reduction of about 60 to 85% of the execution time in the
"extraction" phase of the programs
- Optimization of the computer
resources
Advantages of the true compiler mode
- Suppression of the time
required for validating the programs
- All the advantages of the
compile-and-go mode
- The
possibility to "freeze" an application by producing an object program,
hence avoiding any possibility of accidental modifications
to the program
- The object-module application
becomes independent of any future change of ULTIM
release
- Possibility to
write subprograms in ULTIM
language and have them called by other programs written
in COBOL, ULTIM,
etc.
Availability
of the compiler:
PC Version:
included without charge with the basic system
Z/os
Version:
offered in two versions at
additional cost:
- The performance
option
allows the compile-and-go mode but not the true compiler mode
- The full compiler allows
the compile-and-go mode as well as the production of object modules
