Re: Escape codes for printer control

[Elvis Pressly <elvisdman@HOTMAIL.COM>]

HMMM... I got your point. You want to write into a file escape
characters that will tell the printer that it is a printer command.
This will look like a .lis file where you will use COPY function to print
the file. Let me see, it has been a long while. I have to dig
my libraries. I know I have done something similar like this but I
believe I have to forced SQR to use HEX character value of the
escape sequences..I'm not sure but I'll get back to you when I find
that program.
