need help with a function in a perl file
 
I use a perl program to carry out functions and need a function added to the program.

this function is to add up numbers on each pass when a selected search is reached. is there any one that can help.
i can paste the program .

Do you have problems with Perl or with algorithm?

Re: need help with a function in a perl file
 
I have a perl program that i need a function added to . it was written by my son-in-law and now needs an additional function. i have not been able to get the function added.
i have been using gw-basic to carry out the task manually but this is laborious and my hands dont type as well these days.
the perl program does a search of htm files and prints and saves results. i need it to do a tally during the passing through the data and storing the outcome into the txt file outcome. i can provide / past both gwbasic function and the perl file if it would help.
(i'm sure it would help)
sorry i missed your reply to my query. hope you are still there.

Yes, I'll need both of then, possibly with explanation of algorithms if comments are missing.

Re: need help with a function in a perl file
 
that was the gw basic algorithm it inputs data from horse.dat under a$(i) and at the end of the name is a number for each name appearance it adds the numbers by subtracting from 9 e.g. where the name ends with 5 it subtracts 9-5 which is 4 this is stored in another variable and the final total is printed at the end after the horse name. there is also a test for a value at the 2nd last character in the name if there is an a on the end. e.g. )7a is tested for a value at the second last character.
sample data "pepinello(good)(1200)(belmont)27-09-98)7" other sample
"naughty boy(2150)(good)(oakbank)13-03-10)7a"

i will post part of the perl file in another post.

Re: need help with a function in a perl file
 
this is part of the perl file.

Code:
#!/usr/bin/perl
# Fred's Race Query
# For each html file, extract race info and horse names,
# then print entries from Horse.dat that match the horses
# TODO
# only print races with one or more of Fred's horses in
# find out why it is so slow, and speed it up
$horsefile = "Horse.dat";
print "Reading Fred's horse data.\n";
open HORSES, "<$horsefile" || die "Cannot open $horsefile\n";
@horses = <HORSES>;  # Is this memory gluttony or what?
print "Studying Fred's horse data.\n";
study @horses;  # optimises data for searching
$raceinfo = 0;  # used to pick out race number etc.
$laststart = 0;  # set to 1 when looking for last start info
$foundmatch = 0;

while (<>) {
 # the info about the race is from the beginning of the body
 # till the time hh:mm. We detect this below by looking for ":".
 # NOTE: it is important that this comes first as later blocks
 # remove the tag we are searching for here.
 if ( grep /<body/, $_ ) {
  $raceinfo = 1;
  print "\n";
 }
 # print race information
 if ( $raceinfo ) {
  chomp;  # remove newline
  # The <hr> is the line on the page where the race info ends
  if ( grep /<hr>/, $_ ) {
  $raceinfo = 0;
  print "\n\n";
  }
  s/<br>/ /g;  # turn a break tag into a space
  s/<[^>]*>//g;  # remove html tags
  unless ( $_ eq "" ) { # print it unless it's blank
                        print "$_ ";
  }
 }
