Hi,

It's difficult for me to inspect your source code without spaces at the beginning. It would be helpful to know which lines are the 67th and 72nd.

Birei.

birei here is the code with line nos.

Code:
           sub freecnt{
            open (PEROUT, "<$grplst") || die ("can not open file!");
            while ($LINEIN3 =<PEROUT>)
            {
             chomp $LINEIN3;
            ($indid1, $a, $b, $c) = split(' ',$LINEIN3);
           # Check flight
             if (($LINEIN3 =~ "flight") && ($LINEIN3 =~ "air"))
                {
                   print "$grpid $indid1 ==> in free pool OK to use\n";
                }
           
           # Check ship
##Line 67           else  if (($LINEIN3 =~ 'ship') && ($LINEIN3 =~ 'N/Grp'))
              {
                      print "$grpid $indid1 ==> in free pool OK to use\n";
                }
           # Check road
##Line 72           else   if (($LINEIN3 =~ "road") && ($LINEIN3 =~ "N/Grp"))
              {
                     print "$grpid $indid1 ==> in free pool OK to use\n";
                }
           
            Check in any group
##Line 77               else
                 {
                   print "$grpid $indid1 ==>  NOT FOUND in Free Pool ---  Check Before Using\n";
              }
           }
           close (PEROUT);
           }

Hi,

Perl use the token 'elsif' instead 'else if'. Try changing them, like this (line 67):
Code:
elsif (($LINEIN3 =~ 'ship') && ($LINEIN3 =~ 'N/Grp'))
              {
                      print "$grpid $indid1 ==> in free pool OK to use\n";
                }

Regards,
Birei
