Hi ,

If i am executing this command from my unix prompt it is working fine and giving me the correct result. But it is not working inside my perl script . it is giving error.

Code:
#!/bin/perl

use strict;
use pcmif;

my $max;

$max = perl -lanF';' -e 'BEGIN{$max=0}{$max = $F[2] if $F[2]>$max}END{print $max}' internal_baseline_data.txt;

----------------

error : Bad name after lanF' at ./test.pl line 8.


Can you please tell me what went worng here...


Thanks in advance

DESCRIPTION

       Each of these functions finds the first element with the maximum magnitude in a complex vector, then puts the real and imaginary  parts	of
       it into max[0] and max[1], respectively.

PARAMETERS

       Each of the functions takes the following arguments:

       max	       Pointer to the first element with the maximum magnitude.

       x	       Pointer to the first element of the source vector.

       n	       Number of elements in the source vector.

RETURN VALUES

       Each of the functions returns MLIB_SUCCESS if successful. Otherwise it returns MLIB_FAILURE.
