I finally decided to upgrade from TCC 13 to TCC 16 and the first thing I tried doesn't work. in v13, I can type "start listen" then press TAB for filename completion and it would show "start c:\cad\bin\listend.exe". in v16, this doesn't work. if I simpley do "listen" then press tab, both versions will display "c:\cad\bin\listned.exe". Seems like filename completion isn't doing extended path search when I try to use with internal commands such as start, copy, move, etc. Maybe there's configuration that I missed going from v13 to v16? Thank you.
