Re: perl string substitution

Hi

Many thanks.

When I tried it myself it didn't work but clearly it does. I may have put a
backslah before the $.

Anyway, thanks again.

Regards
John

In string substiution can those two patterns be strings, such as

my ($a,$b,$c);
$a="some string"; $b="another string";
$c =~ s/$a/$b/g;

Thanks
John

Yes. You can easily try this for yourself. Start up the perl debugger
with perl -de1. Here is a session I did to test your question:
DB<1> $a = 'this'

DB<2> $b = 'that'

DB<3> $c = 'this is a string'

DB<4> $c =~ s/$a/$b/g

DB<5> print $c
that is a string
DB<6>
