Note: REXX must be installed on your system for this program to work. REXX is installed by default, but if you did not install it, then run Warp installation again and selectively install REXX support.
rxRTCtrl.DLL requires the presence of the following statements in the CONFIG.SYS:
IOPL=YES,FXPRINT
DEVICE=D:\OS2\BOOT\TESTCFG.SYS
These statements are present by default on any OS/2 Warp 3.0 or Warp 4.0 systems.
If you write your own REXX programs, only rxRTCtrl.DLL is required to access the I/O. I suggest to keep rxRTCtrl.DLL in the same directory as your REXX program so it will be able to find it when rxRTCtrl.DLL is loaded.
As an alternative, put rxRTCtrl.DLL into a directory called out by the LIBPATH in the CONFIG.SYS. A reboot is required for this. Any program loading rxRTCtrl.DLL will then automatically find it.
The following files belong to this program:
