Opens a symbolic data type file and sets up pointers to the symbolic
debug records. Syntax | |
SYMOPEN filename [symname]
|
The SYMOPEN command must be used to open a symbolic data type file before
the symbolic formatting command and functions can be used. Parameters | |
- filename
The file name of the symbolic data type file. The file must contain
symbolic debug records. - symname
The symbolic name under which the symbolic data type file is referenced in the formatter commands. If this parameter is omitted, the file name will be used as the symbolic name.
Examples | |
$nmdat > symopen SYMOS.PUB.SYS OS
$nmdat >
|
Open the symbolic file SYMOS.PUB.SYS and assign the symbolic name OS to it. Limitations, Restrictions | |
Before a symbolic data type file is ready to be opened with SYMOPEN, ensure that the following steps have been followed: The types must be compiled with the $SYMDEBUG 'xdb'$ option. The program containing the types must have at least one statement. The relocatable library generated by the compiler must be run through
LINKEDIT. The program file generated by LINKEDIT must be run through PXDB. The modified program file generated by PXDB must be prepared with SYMPREP in
DAT or Debug. The program file (symbolic data type file) is now ready to be
opened with SYMOPEN.
| | | |  | CAUTION: The output format of all System Debug commands is subject to change
without notice. Programs that are developed to postprocess
System Debug output should not depend on the exact format (spacing,
alignment, number of lines, uppercase or lowercase, or spelling) of
any System Debug command output. | | | | |
