okay so my job is requiring me to learn perl and i have never had any type of programming language... ever.
So i need to take a file that has data (nodes/points) with x, y, and z components.
Example of what the file contains is below:
Code:
RANDOM TEXT
RANDOM TEXT
Node # x pos ypos zpos
5948 50.24 125.35 5.79
(there are over 200 lines of this data)
RANDOM TEXT
RANDOM TEXT
i need to somehow open this file, grab the data for Node, x position, y pos, and z pos and from this data be able to calculate which node is closest to a given position by a user defined input.
so if the user enters a position of lets say 10 for the x pos, 10 for the y pos, and 10 for the z pos. (just keeping it simple) the code needs to be able to loop through the data and find the node with the closest corresponding positions.

perl::prereqscanner::scanner::perl5
Perl::PrereqScanner::Scanner::Perl5(3pm) User Contributed Perl Documentation Perl::PrereqScanner::Scanner::Perl5(3pm)NAME
Perl::PrereqScanner::Scanner::Perl5 - scan for core Perl 5 language indicators of required modules
VERSION
version 1.012
DESCRIPTION
This scanner will look for the following indicators:
o plain lines beginning with "use" or "require" in your perl modules and scripts, including minimum perl version
o regular inheritance declared with the "base" and "parent" pragmata
Since Perl does not allow you to supply a version requirement with a "require" statement, the scanner will check the statement after the
"require Module" to see if it is "Module->VERSION( minimum_version );".
In order to provide a minimum version, that method call must meet the following requirements:
o it must be the very next statement after "require Module". Nothing can separate them but whitespace and comments (and one semicolon).
o "Module" must be a bareword, and match the "require" exactly.
o "minimum_version" must be a literal number, v-string, or single-quoted string. Double quotes are not allowed.
