in reply to while loop returning numbers not strings

See split.

from perldoc -f split:

split /PATTERN/,EXPR,LIMIT split /PATTERN/,EXPR split /PATTERN/ split Splits the string EXPR into a list of strings and returns +that list. By default, empty leading fields are preserved, and +empty trailing ones are deleted. (If all fields are empty, they +are considered to be trailing.) In scalar context, returns the number of fields found. ....

Try splitting to an array, @words and printing them....

#!/usr/bin/perl use 5.014; # 1007352 # error here: $word = split "", $lines; my $lines = "foo bar baz bat read the docs; they're often helpful."; my @word = split "", $lines; # $word replaced with @word say @word;

OR (perhaps preferably)

#!/usr/bin/perl use 5.014; # 1007352 # error here: $word = split "", $lines; my $lines = "foo bar baz bat read the docs; they're often helpful."; my @word = split " ", $lines; # $word replaced with @word; "" replace +d with " " my $word; for $word( @word) { say $word; }
