Hi. Can you see why this isn't working as expected? `use warnings; use strict; my $string = "this is a test \$placeholder"; $string =~ s/\$placeholder/test_sub()/e; print $string; sub test_sub { print "hello there"; }` [download] # prints "hello therethis is a test1 I don't want the subroutine to print anything, just do everything it needs to do and print out all output back into the $string	[reply] [d/l]

Change print to return, and it works. `use warnings; use strict; my $string = "this is a test \$placeholder"; $string =~ s/\$placeholder/test_sub()/e; print $string; sub test_sub { return "hello there"; }` [download] If you really need to capture the output of what a sub `print`s, that's a whole other problem. I was doing something like that in Use of uninitialized value in open second time but not first., and there's more discussion with it about other ways to do it.	[reply] [d/l] [select]
