Notes
Program, Class and method names
• The COBOL system uses, internally, names that start with two underscores
(__). A program, class or method name that starts with two successive
underscores may already have been used as an internal name.
• The following names cannot be used:
- MAIN, main, JMP???, COB_???, COBOL_???, COBW3_???
- Names described in Appendix G: “Subroutines Offered by NetCOBOL” in the
“NetCOBOL User’s Guide”.
Warning error on RAISING phrase
Compile error "JMN3448I-W" may be issued on a RAISING phrase in an EXIT
METHOD statement. This is a result of adding the RAISING phrase to the
PROCEDURE DIVISION header. However, the error does not affect program
execution. Refer to the "Procedure Division Header" section in the "NetCOBOL
Language Reference" for details.
Fixed format
When compile option SRF(FIX[,FIX]) is specified and the source record length is
greater than 80 bytes, earlier versions of the compiler assumed that the part
beyond column 81 was the next record. In this version, the compiler ignores the
part beyond column 81.
Stronger Checks on LINKAGE SECTION Items
In NetCOBOL, the COBOL compiler checks for illegal references to data items
defined in the LINKAGE SECTION at compile time. As a result, programs that
compiled correctly with earlier versions of Fujitsu COBOL may now generate one of
the following compilation errors:
• JMN3482I-S: Illegal use of a data item defined in the LINKAGE SECTION of a
called program, method, or second entry point.
• JMN3483I-S and JMN5595I-S: Illegal use of a data item defined in the
LINKAGE SECTION of the main program (the command line argument of OSIV
format).
If these errors are output, the program should be corrected as follows:
• When JMN3482I-S is output
If the data item indicated by the diagnostic message was used as a parameter
for a called program, method, or second entry point, correct this by specifying
the data item in the USING/RETURNING phrase of the PROCEDURE DIVISION
(for programs and methods) or USING phrase of the ENTRY statement (for
secondary entry points). If the data item is not used for this purpose, you
should define it in the WORKING-STORAGE SECTION.
• When JMN3483I-S or JMN5595I-S is output
