Thanks to all that helped with this problem, and thanks especially to
RandyS as he hit the nail on the head. Here is the final working code
block below.
while (LOGFILE) {
chop $_ ;
if( (/JUNIPER/) || (/REDBACK/) ){
print DSL $_ . \n;
} else {

So you are saying that the characters ':', 'p', 'r', 'i', 'n' and 't'

What a quick response. Thanks.
No problem.

Would something like this do the trick?

True. But I need to test the line to see if it contains
those '*--**'. Otherwise how do I know that
