Hello,
this one has been driving me nuts and I'm sure it's something very
simple I maybe overlooking. I need to assign a delimiter variable IE:
Pipe or Comma delimiter:
my $del = '|'; # use either a '|' or ','
my $dataline = "0|1|2|3|4|5|6|7|8|9";
my @data = split(/$del/, $dataline);
This does not work, it won't split the file line with the '|' delimiter,
and get no errors. But if I do this:
my $dataline = "0|1|2|3|4|5|6|7|8|9";
my @data = split(/\|/, $dataline);
Then it works prefectly, it splits the line as expected. What am I
missing ??
Hello,
Change one of the lines to:
my @data = split(/\Q$del/, $dataline);
This would work.
