ENABLE Reference Manual

APPENDIX D
MODIFYING THE SCREEN COBOL SKELETON FILE
You can modify a copy of the SCREEN COBOL skeleton file provided
by ENABLE and use this modified version to generate an
application. The SCREEN COBOL skeleton file contains source text
for a SCREEN COBOL program that is complete except for the data
items defined by DDL record descriptions and options included by
the ENABLE compiler.
Special command lines in the skeleton drive the ENABLE
processing. These command lines are interspersed with text
lines. Before you attempt to modify SCREEN COBOL code that is
controlled by these special command lines, you should understand
the effect of the modification. When you modify a special
command line or add a new command line, you do so at your own
risk. Because the skeleton contains comments at the beginning
that explain how these special command lines work, this manual
does not explain them.
If you make an error when you modify a command line, ENABLE
terminates with a diagnostic message indicating the edit line in
the skeleton file containing the error.
To modify the skeleton, you must obtain a copy of the skeleton
file. The skeleton file resides on a file named ENABAPPS.
Normally, this file resides on $SYSTEM.SYSTEM. If ENABAPPS does
not reside on this volume and subvolume, ask your system manager
to tell you the location of this file.
Duplicate a copy of ENABAPPS and make your modifications to this
copy. To use the copy when you generate an application, use the
SET APPL SCOBOLSKELETON command.
The following list describes some possible modifications to the
SCREEN COBOL skeleton file:
