Ha, while experimenting with the best error message I just found out, that
OLEObject~new will give
the very understandable error message:
F:\work\svn\oorexx\main\trunk\samples\windows\ole\apps>samp05.rex
*-* Compiled method "INIT" with scope "OLEObject".
*-* Compiled method "NEW" with scope "Object".
51 *-* Method NEW with scope "OLEObject" in package "REXX" (no source
available).
52 *-* WordProApp = .OLEObject~New("WordPro.Application")
Error 98 running REXX line 51: Execution error.
Error 98.909: Class "WordPro.Application" not found.
This is very instructive and makes my first question obsolete as there is no
reason to change the
samples directly with respect to the error! :)
The only remark with the error above is line # 51 which is not a Rexx
sourceline and also maybe its
two preceding lines should not be shown in this case either?

Still, I would like to change the Excel sample09.rex, if no one objects!
