[fpc-pascal]Reading the screen

[Matthew Bradford]

Jim,
I looked around the docs and couldn't find anything that would help you, 
however, I think I still may have a solution for you.

If you want to write something to the console you can write a wrapper 
for the writeln procedure that would do the following:
1. behave like the current write/writeln procedures do
2. in addition, keep track of all screen writes in an array
eg. var Screen[1..80,1..25] of char;
Now, that could get kind of tricky when you start throwing in windows 
and such.  But, for straight screen writing and no fancy stuff, that 
should do the trick.  Also, it wouldn't be all that hard to write it so 
that the array would totally mimic the screen.

A second option, is pick up an assembler book and call the interupt that 
will return that info for you. (A word of caution on that though. 
Interupts are slow, so if speed is important, that would not be the way 
to go.  Also, the use of assembler makes your program very non-portable. 
However, if neither of those are a concern for you it would probably be 
easier.)

Perhaps one of the more experienced people with FPC will have better 
insight into a way to do this that is already built into the language.

Matt
