The command (cmd) program automaically executes program with extension specified in PATHEXT variable. It is typically defined as follows PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC

Since the crossmeta commands in v:\bin directory have case-sensitive extension .exe to them, it is required to specify the full filename with extension to run them. If preferred you can add .exe to PATHEXT so that it can be run without specifying any extension name. set pathext=PATHEXT=.COM;.EXE;.exe;BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.MSC
