"Note that the map source (.src) files contain UNIX style line breaks (line feed = 0x0A) which need to be replaced with Windows style (carriage return + line feed = 0x0D0A) before they can be processed using QBasic scripts" That's easy to do. Simply open them in Wordpad and save as text files. It replaces the line endings with the DOS/Win style CR/LF.
Noted, thanks !
