ipar [-option] filename[, ...]
Options
option
(optional) One or more of the following:
Display brief output by suppressing comments. This makes it possible to compare the output from multiple issuances on the same or a similar file.
Generate a parameter file (or an XDL/FDL file if the -x option is also specified) that has the same name as each ISAM file for which you want a description but with the extension .par (or .idl). If both -x and -g are specified, the filename extension is .xdl.
Generate an XDL or FDL file to the terminal.
filename
The name of the ISAM file(s) for which you want to generate parameter file descriptions. The default extension is .ism.
The ipar utility generates parameter file descriptions of existing ISAM files, which you can then use as input to bldism to rebuild the same files. These descriptions contain current content information about the specified ISAM file in their comment lines.
If you don’t specify any option, ipar sends parameter information to the terminal by default.
If ipar detects an .is2 file, it generates a warning message but generates the file description anyway.
Examples
The following example generates a parameter file named file1.par for file1.ism and a file named file2.par for file2.ism:
ipar -g file1 file2
The next example generates a parameter file with the extension .par for each of the ISAM files in the current directory:
ipar -g *.ism
The following example generates parameter information for our ISAM file, cusmas.ism:
ipar cusmas
This example sends the following information to the terminal:
