Hi Guys,
I built a 144 LED scrolling message display:

It's message data is compiled by a PSP program that converts a message
string input through the OSK to a monochrome bitmap in the correct format
to be written to the EEPROM in my LED circuit.
The monochrome bitmap is 8 pixels high, and has the potential to be
tens of thousands of pixels wide.
I have a blog thing happening here:

The trouble I have with the OSK is the input string has a 50 character limit.
Is there an easy way to lift this?
Otherwise I can hard code a long message, but in the end I'll have to
knock up another of my own character input routines.
Art.
OSK 50 Char Limit?

If not actually, then potentially.

This is the source code to the OSK, find the formal parameter or implementation for the string input, and jack it up some.
If not, I don't see any other way, except accepting the input and adding the string to another character array, storing it, and then appending more, and more OSK input until you're satisfied with the length. Next, nulling the last bit, then passing it off to the other program meant to make the monochrome.
