If you want to transfer the file to a different machine, especially a different platform then you need to use the FORMCHK utility that converts the binary file into a formatted ascii file. The conversion should be done on the machine that created it. If you want to use the file in a Windows environment, then you'll need to run UNIX2DOS command (it replaces the Line Feed (LF) ascii code with Carriage Return (CR) Line Feed (LF) used by Windows), before FTPing it to the Wondows machine. There is Unix2dos utility for Windows called Tofrodos (http://www.thefreecountry.com/tofrodos/) if you wish to do the Unix-DOS conversion under Windows/DOS.
