and pointed out that this was flawed. Dare I suggest replacing the first line
with :

if find(s,"EOF") then

Jiri wrote that you can and always will be able to use return to escape from
procedures. This is funny because I recently got clobbered by the interpreter
for trying to "exit" from a procedure (Yes, I guess I learnt it from [excuse
my language] QBasic). However, we have

"exit"
from loops
"return"
from rountines and
"abort"
from main routine.

Is this not an unnecessary complication ? Would it hurt anyone to allow "exit"
from a procedure Rob ? I think that having "return x" in a procedure would be
extremely confusing for a newbie and hints of other inferior languages which
allow you to do naughty things like not returning values from functions.
