RE: v 2.4.2 echos \r file

[cino hilliard <hillcino368@hotmail.com>]

Hi,
Thanks.
 
It looks like the scripts now have to have an ending semicolin for return values,
if statements and for statements. For the while statement, this was always required
anyway.  I went through 1000 lines in util2.gp file of 100 or so functions and did this
and now \r util2 works fine.
(07:04:57) gp > \r util2
(07:14:37) gp >
 
It looks like I will have to be a better programmer.:-)
 
Cheers and Roebuck,
Cino
