The EQUEL Preprocessor Command
The Pascal preprocessor is invoked by the following command line:
eqp {flags} {filename}
where flags are
-d
Adds debugging information to the runtime database error messages generated by EQUEL. The source file name, line number, and the erroneous statement itself are printed with the error message.
-f[filename]
Writes preprocessor output to the named file. If the -f flag is specified without a filename, the output is sent to standard output, one screen at a time. If the -f flag is omitted, output is given the basename of the input file, suffixed ".pas".
-l
Writes preprocessor error messages to the preprocessor's listing file, as well as to the terminal. The listing file includes preprocessor error messages and your source text in a file named filename.lis, where filename is the name of the input file.
-lo
Like -l, but the generated Pascal code also appears in the listing file
-n. ext
Specifies the extension used for filenames in ## include and ## include inline statements in the source code. If -n is omitted, include filenames in the source code must be given the extension ".qp".
-o
Directs the preprocessor not to generate output files for include files.
This flag does not affect the translated include statements in the main program. The preprocessor will generate a default extension for the translated include files statements unless you use the -o.ext flag.
-o. ext
Specifies the extension given by the preprocessor to both the translated include statements in the main program and the generated output files. If this flag is not provided, the default extension is ".pas".
If you use this flag in combination with the -o flag, then the preprocessor generates the specified extension for the translated include statements, but does not generate new output files for the include statements.
-s
Reads input from standard input and generates Pascal code to standard output. This is useful for testing statements you are not familiar with. If the -l option is specified with this flag, the listing file is called "stdin.lis". Type Ctrl Z to terminate the interactive session.
-w
Prints warning messages
-?
Shows the available command line options for eqp
The EQUEL/Pascal preprocessor assumes that input files are named with the extension ".qp". This default can be overridden by specifying the file extension of the input file(s) on the command line. The output of the preprocessor is a file of generated Pascal statements with the same name and the extension ".pas".
If you enter the command without specifying any flags or a filename, Ingres displays a list of flags available for the command.
The following table presents the options available with eqp.
