I would recommend to avoid using RUN. There are situations when it does not work, and it is hard to find the cause. Try shellexec or winexec API instead. Something like:
DECLARE INTEGER ShellExecute ;
IN SHELL32.DLL ;
INTEGER nWinHandle,;
STRING cOperation,;
STRING cFileName,;
STRING cParameters,;
STRING cDirectory,;
INTEGER nShowWindow
?ShellExecute(0,"open",fullpath("btest.bat"),"","",1)
