Win XP Pro SP 3 TC and TCC 9.02 bld 153 START "name" /pgm "c:\some\directory\program.exe" -arguments for program Fails with TCC: (Sys) The system cannot find the file specified. "C:\SOME\DIRECTORY\PROGRAM.EXEe" when the file exists. When the file does not exist the name of the file in the error message does not have the extra 'e' at the end. This worked correctly in build 149 (which was the last version I had used). It makes no difference whether the start command is issued at the prompt or from a command file, nor whether the filename is in upper or lower case (but the 'e' at the end is the same case as the last character in the original command), nor whether the filename is absolute, relative, or constructed with environment variables or variable functions. It also makes no difference whether there are arguments or not. No alias for START, of course.
