Yes, that did the trick.

Ok I think my setup is not standard and causes the error.

E:\...es\Progr\C\slang-pre2-r5\src\test>sltest dollar.sl
Testing dollar strings ...Failed: %$1${}%, found "%Dollar-1/K
E:\os2tools\os2ini
t.cmd%"
Traceback: error
Traceback: verror
***string***: Run-Time Error
Traceback: failed
.\inc.sl: Run-Time Error
   Local Variables:
         String_Type s = "%$1${}%, found "%Dollar-1/K
E:\os2tools\os2init.cmd%""
.\dollar.sl:78: Run-Time Error
.\dollar.sl:80: Run-Time Error
Run-Time Error


When I look at my environement I use a seldom used feature of OS/2. I have

SET OS2_SHELL=C:\OS2\CMD.EXE /K E:\os2tools\os2init.cmd

defined in Config.sys.

This defines cmd.exe as the commandshell but calls os2init.cmd whenever
a new OS/2 VIO session is started. In this init script I set Window size
and modify the commandprompt.

Yes this solved the problem

E:\...es\Progr\C\slang-pre2-r5\src\test>sltest dollar.sl
Testing dollar strings ...Ok

    Ciao,  Hannes
