Using VFP6 SP4

Are there any article on string manipulation in VFP6?

I need to write a generic routine to parse any text file into 80 character lines and output these lines into a new text file, for sending up into a mainframe.

I am currently grabbing the file with the STRTOFILE() into a memvar then I go through each character 1 character at a time to create this file. I also do some other testing but this is the idea.

However, this technic seems slow, especially on a large text file.

Any help would be great.

Thanks,
