I have a "warning in loops" for you guys...
Check this "stupid" routine:

;---------------------------------------
print,'Integers'
J = 0
for I = 1,10 do begin
print,I
I = I + J
endfor

print,'Float'
J = 0.0
for I = 1,10 do begin
print,I
I = I + J ; Here I am changing the Type of "I"
endfor

print,'Long'
J = 0L
for I = 1,10 do begin
print,I
I = I + J ; Here I am also changing the type of "I"
;if i gt 20 then stop
endfor
end
;----------------------------------

The first loop if OK, the second loop stops after the first
iteration, but the last loop, just keeps going forever...

Any comments ?
At least should be a "WARNING" in the manual...
