One way to beat this, and still allow you to use a single space as an exit
character, would be to create a loop that inputs a single character, then
tests if that character is a space. If so, exit the loop, if not, append
that character to the end of a string, eg
InputtedValue = ''
Loop
Input Val,1:
if Val=' ' then exit
InputtedValue := Val
Repeat

This is correct, as is the rest of Dennis' post; but I'll add one
caveat. When I've written this sort of loop, it's often been necessary
to add a sleep or delay in the loop. Otherwise when this process is
executing the computer can use the user's entire timeslice looping,
'cause there's always something for the computer to do. Which will tend
to bog the machine down for the other users, (much as a very intensive
SELECT will do).
Obviously this can also be dependent upon userload, hardware, operating
system and Pick/U2 variant - some combinations work better than others.
