perl -write num array and string array from dataFile
Locking this thread would be a travesty.. Newbies like myself need these strings of information to help elevate us to a higher level of understanding of a lang seasoned programmers take for granted.
This is my first post to unix.com.. a true newbie.
++++++
From what I have read through this string I have been able to read in a file to an array and print it back to console.
open(FILE, "<", "dataFile");
my @dataValues=<FILE>;
close(FILE);
print("\n@dataValues");
What I would like to do now is take a data file
AAA
BBB
CCC
1
2
3
and read strings into @stringArray and read the int into @intArray. Should be simple.. just have not been able to figure it out..
