The "pre2ncgm" command reads a pre-CGM NCAR metafile from standard input and writes an NCAR CGM file to standard output. When plotted, the output file should have virtually the same appearance as the input file.
When this option appears, all text and header records which appear in the input file (created by PRSIM) are not copied to the output file.
pre2ncgm < input-file > output-file
causes "input-file" (which should be a pre-CGM NCAR metafile) to be read and the equivalent NCAR CGM file to be written to "output-file").
Various errors are detected by "pre2ncgm" and are written to /dev/tty.
