-----------------------------------

either....
loop
exit when hasch
end loop
or
Input.Pause
the way it is written for hasch, will stop the program until a key is pressed(because it is processing and "empty" loop) but you can include in another loop, say to exit at any time.
Input.Pause just stops everything until a key is pressed. you dont need to hit enter for either

why not just use:
var ch : string (1)
getch (ch)

Santa's solution is better. The problem with just using hasch is that the key will not be processed...meaning that it won't work if you try it again (because hasch will still be true)

wow, your right....it wont work again. I forgot to take into account that the input buffer already has a key from the last loop, and is therefore carried on to the next loop....very perseptive Mckenzie! So just go forth and use the *getch (key )* command...it alwa ys works...or combine them:

if hasch then
getch(key)
end if

(psst) Dodge, I think your wrote that in the wrong topic (psst)
And yes...he kind of has to. CompScience gets very boring when your marking kids' programs which you can usually do 100x better...

-----------------------------------

see but you can have multiple

loop
exit when hasch
end loop

's so that itll stop at that one spot.. and if he doesnt need the char for anythin, input.pause is faster to write :), with no variable needed

-----------------------------------

so mackenzie using Input.Pause won't work more than once either?
also isn't there a command or a way of emptying the characters that have been inputed?

whats the program being made? is it like

drawoval(x,y,25,25,7)
put "Press any Key to continue."
%code here(whichever method you use)
draw box(x1,y1,x2,y2,7)



because if so, Input.Pause works, you dont need to declare a variable, and you dont need a loop or anything.
