hp Micro Focus COBOL
4.x compiler impacts summary
 |
| |
|
The COBOL language does not change much over time. Hence, not many
COBOL-specific transition impacts exist. Most impacts in COBOL source
are for cross-language and platform dependencies, such as calls to C
routines and operating system commands.
|
COBOL-specific impacts are relevant only if you are making the transition
from the COBOL 3.1.x compiler to any version of the COBOL 4.x compiler. Most
of the compiler changes actually occurred between versions 3.1.x and 3.2.x,
so if you are already using 3.2.x you can ignore these impacts.
11.x COBOL changes include:
- Object file incompatibility: .snt object files were replaced
with .gnt files. Old .gnt files could only be shared
within a process. New .gnt files are now loaded as shared
libraries and are shared across processes, like the HP-specific
.snt object files were shared previously. The STK file scanners
cannot detect object file incompatibilities; see the HP Micro Focus Object COBOL/UX Release Notes for Version
B.13.35 or HP Micro Focus Object COBOL/UX Release Notes for Version
B.12.35 for information.
- Source incompatibilities: Many new reserved words have been added. All
Motif functionality has been removed, including the graphical mode version
of the Dialog System and the Fileshare View utility,
fsviewmot.
Note: To include only HP Micro Focus COBOL 4.x compiler impacts
when running the scansummary and scandetail
tools, use the option:
+C CBL4
To exclude these impacts, use the option:
-C CBL4
