I am trying to split the first element of an array by white space then continue reading the rest of the file. Thus far I am having trouble figuring out how to split the first line.
I would like the first line to be split so it looks like the following with the "=" sign added. Thank you in advance! Chris csno= rfpi= header_1= header_2= header_3= header_4= header_5= header_6= header_7= header_8= header_9= I am getting the error: Use of implicit split to @_ is deprecated at ./xxxxx.pl line 6. #!/usr/bin/perl use warnings; use strict; while (my @line = <DATA>) { my $header = split " ",$line[0]; print $header; } __DATA__ csno rfpi header_1 header_2 header_3 header_4 header_5 header_6 header_7 header_8 header_9 1 1 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 1 2 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 1 3 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 2 1 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 2 2 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 2 3 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 3 1 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 3 2 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 3 3 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 4 1 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 4 2 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 4 3 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5 5.5
