Hi Richard,
The script below is fine running in my own apps :
open file thefile for read
read from file thefile until eof
put line 189 to 300 of it into b
close file line 1 of the openFiles
If your platform is unix and this script don't run on it, just set the
read permissions of the file to "yes" and it will run again...
Have fun and a big and good new millenium...
Pierre
