May i know if the below code is added , will it set all the rest of the base array index to 1 or does it just apply to the particular array @Marks only ?
Code:
$[ = 1;
Another question is that my "reports_${counting}_${_[0]}.txt" file has the below contents, however if i put the index to be the below in red, i would NOT be able to capture the correct $lotsuffix variable ? Why is this so ?
hi

This finds $regex and print... (3 Replies)

array::printcols
PrintCols(3pm) User Contributed Perl Documentation PrintCols(3pm)NAME
print_cols, format_cols - Print or format array elements in vertically sorted columns.
SYNOPSIS
"use Array::PrintCols;"
"print_cols @array;"
"print_cols @array, $colspec;"
"print_cols @array, $colspec, $total_width;"
"print_cols @array, $colspec, $total_width, $indent;"
$output = "format_cols" <same arguments as "print_cols">;
"$Array::PrintCols::PreSorted = 0;"
DESCRIPTION
This module exports two subroutine names: "print_cols" and "format_cols".
The "print_cols" subroutine prints the items of "@array" in multiple, alphabetically sorted vertical columns. One, two, or three optional
arguments may be given to "print_cols" to control the width and number of the columns, the total width of the output, and indentation.
Reasonable defaults apply in the absence of the optional arguments (or when given as the empty string or zero). Generally, the minimum
width column is used when possible.
If "$colspec" is given as a non-negative number, it is treated as the minimum width of the column; the actual width will be the maximum of
this value and the lengths of all array items.
If "$colspec" is given as a negative number, its absolute value value is used to determine the total number of columns. However, it cannot
exceed the total number of columns possible based on the maximum length of all the array elements.
If a third argument is supplied, it is used as the total width of the output. The default for this value is the value of the environment
variable $ENV{'COLUMNS'}, if defined, or 80.
If the fourth argument is given, it is used as the indent for all lines printed, which subtracts from the total width of the output. This
value defaults to zero (ie: no indention of the output).
The variable $Array::PrintCols::PreSorted controls whether or not the "print_cols" subroutine will expect its array argument to already be
sorted. If this variable is nil or zero, "print_cols" will cause print out a sorted copy of the input array.
The routine "format_cols" is called exactly like "print_cols" but returns the formatted result as a string, rather than printing it.
EXAMPLES
use Array::PrintCols;
@commands = sort qw( use list put get set quit help server );
# print in three columns with an indention of 1.
print_cols @commands, -3, 0, 1;
# print the formatted result data to the result file
print RESULTFILE format_cols @result_data;
