in reply to a dumb question

Okay, I've poked around with it a bit, and your concern really seems to be whether your quoting characters are being preserved. The following code snippet demonstrates that the quoting is preserved: 
#!/usr/bin/perl -w
use strict;

my $foo = sprintf("\"|%s\"",'Bar');
print $foo, "\n";
my $bar = qx{echo $foo};
print $bar, "\n";

(If the quoting wasn't preserved, the | would generate an error)

So it really looks like it isn't the qx{} that is introducing the error, although it still many not be passing what you expect...Could you show us an example of the expected output?

    I changed the qx to qq and displayed the string as it is built. The result was exactly as I expected. I even cut and paste the generated string on the command prompt and it executed with the expected results. Here is the generated string: aml_read /l trace /h FTWAEIPD0001 /s "12/04/2000 07:00:00" /b "12/04/2000 08:00:00" /d all /appl commproc | egrep -c -e tty2

    ....Which once again should be generated from this: 

    $tty = qx{aml_read /l trace /h $_[3] /s $_[1]  /b $_[2] /d all /appl c
+ommproc | egrep -c -e $tty_string};
printf("<TR ALIGN=LEFT VALIGN=TOP>\n");
printf("<TD>%s</TD>\n",$tty_string);
chomp($tty);
printf("<TD>%d</TD>\n",$tty);
printf("</TR>\n");

    What is also weird is that I can hardcode the variables in the query and get the same results (although it seems to only work outside the loop). I suppose it is possible that I have more than one problem. One problem could be the qx line and the loop may also have errors.

    Thanks Bryan

      What does the output from aml_read look like? Does the web user have permission to run it? Also, it seems a waste to run the command for every tty # when you could tally the results from one run.

      It should also be noted that this problem didn't start occurring until we upgraded the server we are accessing (FTWAEIPD0001) to AIX 4.3.3 ....... in my opinion it is indirectly related to that.

      thanks again, Bryan
