- This document describes the sample program files, which are installed
- in the SAMPLES subdirectory.
-
- Several programs use the dBASE for Windows Form syntax, which lets
- you run multiple programs simultaneously. For example, start openform.prg
- by either typing DO OPENFORM in the Command window or double-clicking on
- its icon in the Navigator. After the openform form appears, you can
- start Winapi.wfm again either through the Command window or Navigator.
- You can then switch freely between the two forms.
-
- All samples should be run from the <_dbwinhome>\samples directory.
-
- There is a SAMPLES.CAT catalog that lists all the samples files described
- below.
-
- Note: The files in the samples\extern, and samples\music
- directories are described in extern.txt, and music.txt,
- which are located in the corresponding diretories.
