# GBMDLGRX - A REXX adapter for the GBM File Dialog

## Introduction

GBMDLGRX is a REXX adapter DLL for OS/2 and eComStation which REXX programs may use to select bitmap filenames to load or save. It uses GBMDLG (GBM File Dialog). Full online help is available via GBMDLG.HLP.

For being able to use it, the following additional files are required:

- GBM.DLL (GBM Bitmap Format Handler)
- GBMDLG.DLL (GBM File Dialog)
- GBMDLG.HLP (GBM File Dialog Help)

## Installing GBMDLGRX

Just unzip the GBMOS2PM package and copy the `gbmdlg.dll` and `gbmdlg.hlp` files into the same directory as `gbmdlgrx.dll`. Get the GBMOS2 package and copy `gbm.dll` into the same directory as `gbmdlgrx.dll`.

As `gbmdlg.dll` needs `gbm.dll`, also `gbmdlgrx.dll` needs it. `gbmdlg.dll` and `gbm.dll` need to be locateable via `LIBPATH` in order to be able to use `gbmdlgrx.dll`. If the online help of the GBM File Dialog should be available, `gbmdlg.hlp` must be locateable via `HELP` variable.
