Using QMF Version 8.1 commands under earlier releases
QMF Version 8.1 procedures and applications might run incorrectly
under an earlier QMF release because they contain commands that
the earlier release cannot run. Some commands:
- Do not exist in the earlier release.
- Contain options that operate differently in the earlier release.
For example, the DRAW command has the same syntax as before, but
now produces different results. All keywords now have double quotes;
therefore, the users no longer have to add the quotes, and any tools
used to provide double quotes are no longer necessary.
