Close... 
#!/usr/bin/perl -w

use strict;

my $file = shift or die "must supply body file";

open F, $file;

my $text  = join '', <F>;
my $regex = '(procedure|function)\b(.*?)\((.*?)\)';

while ($text =~ /$regex/mgs) {
  print $1,$2,"($3);",$/;
}

The m is important to enable multi-line matching, or your regex will not scan across newlines.

    Actually m made no difference in output. And what I had was working, it's just that the word "function" was in a comment and my regexp was lapping it up, so I will simply filter comments from the text before parsing it: 
    #!/arudev/bin/perl

use strict;

my $file = shift or die "must supply body file";

open F, $file;

my @text  = <F>;

my $text  = join '', grep { ! /\s+\-{2,}/ } @text;

my $regex = '(procedure|function)\b(.*?)\((.*?)\)';

while ($text =~ /$regex/gs) {
  print "*$1+$2-$3*",$/;
}
