LFRM
Remove Linefeeds

LFRM is a C++ program which removes linefeed characters from a file.

I constantly run into problems, when transferring a file from one system to another, involving different conventions for ending a line of text.

It is my understanding that the following "conventions" apply:

• Macintosh (pre OSX) text lines end with the CR (carriage return) character;
• PC text lines end with the CR+LF (carriage return + line feed) characters;
• UNIX text lines end with the LF (line feed) character;

While your file transfer program will usually transfer a text file in such a way that that carriage control is properly translated, this sometimes doesn't happen, especially if the text file is transferred "verbatim", that is, as though it were a binary file.

In such a case, LFRM is the correct program to use if you want to convert a PC text file to a Macintosh (pre OSX) text file, since it will replace each occurrence of CR+LF by CR.

The user will be prompted for the output file.

lfrm

The user will be prompted for both files.
