Wasn't it something like Request() and RequestStr()? I'm not sure anymore.

Its: Request "x",a
Or for Strings: RequestStr "x",a
x is the message which is displayed
a is the name of the new variable which is given a value

up to now I've seen strings only in the function/prgm("hereismystring1","hereismystring2",...)
but not in the middle of the program to get strings...

You can use it par example like this

...
RequestStr "Name",name
...
Text "As the dusk arrived you heard someone shout"&name&",irritated you turned around..."
...

hope this doesn't sound to educational
