The EQUEL Preprocessor Command
The BASIC preprocessor is invoked by the following command line:
eqb {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 along 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 ".bas".
-iN
Sets the default size of integers to N bytes. N must be 1, 2, or 4. The default setting is 4.
-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
Similar to -l, but the generated BASIC 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 ".qb".
-o
Directs the preprocessor not to generate output files for include files.
This does not affect the translated include statements in the main program. The preprocessor will generate a default extension for the translated include file 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 ".bas".
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.
-rN
Sets default size of reals to N bytes. N must be 4 or 8. The default setting is 4.
-s
Reads input from standard input and generates BASIC 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." To terminate the interactive session, type Ctrl Z.
-w
Prints warning messages
-?
Shows what command line options are available for eqb
The EQUEL/BASIC preprocessor assumes that input files are named with the extension ".qb". 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 BASIC statements with the same name and the extension ".bas".
If you enter the command without specifying any flags or a filename, INGRES displays a flags list for the command.
The following table presents the options available with eqb.
