I am interested to create a folder B in D drive of computer and
then save results in a text file (Result_File.txt) inside B folder
using perl. For this I have written the following script p5.pl but
the cmd has shown an error. I am at my wit's end to find a solution. I
searched in perldoc but couldn't find the code applicable in my case.
I can't make out what the technical term perlIO layer really means
in the error message in cmd. May I request PerlMonks to provide
suggestions in this matter?
Here goes the script p5.pl:
my $a=9; my $b=5; my $c=$a*$b;
## Create the folder B in D drive & Save results as Result_File.txt
# within B folder:
open (my $fh,">D://B/",$output) or die"Cannot open file'$output'.\n";
+# Line 10
print $fh "\n WELCOME! Product of 9 & 5= $c\n\n";
Here goes the error message in cmd screen:
Unknown PerlIO layer "D" at C:\Users\x\Desktop\p5.pl line 10.
Cannot open file'Result_File.txt'.
