EVRexx is a package of external functions for REXX-programs. EVRexx enables the use of PM dialog-windows from your REXX-application. Source code included.
This package was inspired by VREXX, a similar package written by R.B.Lam of IBM T.J.Watson Research Center.
VREXX has a number of limitations which are overcome with EVRexx:
- EVRexx can be used by more than one process at a time.
- With EVRexx you can (and must) define your own dialog windows. Therefore it is possible to mix controls.
- EVRexx allows modeless dialog windows.
- Recovery of system resources in case of fatal (REXX-) errors.
- Dialog windows are entered into the window list.
The price you pay for all the enhancements of EVRexx is that the package is not quite as easy to use as VREXX. In addition, the graphic capabilities of VREXX are not yet implemented in this release of EVRexx.
