Thanks for your prompt response.
I have my Dell computer divided into two [separate] partitions: Dos 6.22 2 GB and WinXP 38 GB. I have downloaded your .prn files to the XP section and in order to post them with Dos command would transfer them to the Dos partition by copying them to the 3.5" diskette a:/ drive.
Don't quite grasp your "If so, do the 'transfer' in a Windows 'command-prompt' session, which will provide many DOS-like command-line utilities." so I go into Start -> cmd ->...??
