bdebugger c:\cmd\cd.btm /? ide does not start bdebugger help is displayed, RC=2 ide c:\cmd\cd.btm /? ide does not start nothing is displayed, RC=2 bdebugger c:\cmd\cd.btm /h ide starts %1 correctly set ide c:\cmd\cd.btm /h ide starts dialog "c:\h was not found" pops up (note / swallowed) %1 is not set ide c:\cmd\cd.btm arg1 arg2 ide starts dialog "c:\arg1 was not found" pops up dialog "c:\arg2 was not found" pops up %1 and %2 are not set And while on this subject (I can't remember if I asked this before) why doesn't alias ide=`*bdebugger %@search[%1] %2$` work? ide cd /h pops up "C:\%@search[cd].cmd was not found". Or if that can't be made to work, why doesn't bdebugger/ide resolve aliases and search the path? I have this workaround, alias 4trace=`keystack ! "bdebugger %@search[%1] %2$" Enter` but its klutzy and sometimes still fails.
