Usage Guidelines
• The COLUMNS pragma can be entered on the compiler RUN command line or in the source
text. If it is included in the source file, the COLUMNS pragma must appear before any SECTION
pragmas.
• The OLUMNS pragma can also be specified with the -Wcolumns=c flag of the c89 or the
c99 utility.
• If you do not use the COLUMNS pragma, the compiler processes the full length of each source
line.
• The COLUMNS pragma can be specified only once in each source file and it must be the only
text in the source line.
• The COLUMNS pragma causes physical source lines after last-column to be truncated before
the C preprocessor begins the translation phase.
• The COLUMNS pragma currently in effect depends on the context:
The main input file uses the last-column value specified in a COLUMNS pragma. If no
COLUMNS pragma is specified, the compiler processes the full length of each source line.
◦
◦ At each #include directive, each included file initially assumes the last-column
value in effect when the #include directive appeared. If a COLUMNS pragma is specified
in the included file, the compiler uses the last-column value specified.
◦ After a #include directive completes execution (that is, after the end of file is reached),
the compiler restores the last-column value to what it was when the #include
directive appeared.
◦ In all other cases, the last-column value is set by the most recently processed COLUMNS
pragma.
CPATHEQ
The CPATHEQ pragma specifies a file to be included before the compiler begins compiling the
source file. The CPATHEQ file is an EDIT file that typically contains MAPINCLUDE pragmas to submit
to the C or C++ compiler. The CPATHEQ file can also be used to provide command-line options
that exceed a single command line, such as SSV pragmas; a CPATHEQ file that contains
command-line options is not treated as part of the command line but as a source file.
CPATHEQ [ "file-name" ]
file-name
identifies a CPATHEQ file.
