Hello Perl Monks,

I have a csv file where I store things like, some table names, functions to execute etc. Sample:

Table1, getTableID('DBO','Table2')

[download]

I am writing a perl program that will read this file. Then when it sees a subroutine (which I can either use a regex or just append it as SUB:getTableID('DBO','Table2'), wherein I will read second portion of string delimited by : to get value as getTableID('DBO','Table2')), from my perl program, I need to execute it as a subroutine and give a return value.

If I simply print the content of file, I will get getTableID('DBO','Table2')

If suppose getTableID('DBO','Table2') returns value 100, I want the perl progrm to print 100 instead of the string: getTableID('DBO','Table2')

view my.csv

Table1, getTableID('DBO','Table2')

[download]

view demo.pl

sub getTableID($$) {return 100;} 

open FH, "my.csv" or die $!;
while(<FH>)
{
chomp;
push(@arr, $_);
}close FH; 
foreach my $line(@arr)
{
my @arr1 = split(",",$line);
my $val1 = $arr1[0];
my $func = $arr2[1];

print $func;
## This prints getTableID('DBO','Table2')
## I want it to actually execute the sub and print return ## value 100
}
