hi,
hmm...i'll try backing up a bit. basically this is what i want to do.
a webpage that screens for stocks. variables from the webpage is sent
to a perl script which displays (in html format) charts based on the values
and parameters passed.
the perl script calls upon another script to display the charts. the
second script
makes a system call to main.exe (the charting program).
ie.
from FirstScript.....
$basicParam = "/cgi/SecondScript.pl?symbol=${symbol};
<img src="${basicParam}&indicator=price&chartType=${chartType}"
${priceImgSize}>
<img src="${basicParam}&indicator=volumn&p1=${p1}&p2=${p2}"
${chartImageSize}>
from SecondScript....
&ReadParse(*para);
foreach $name ( keys(%para) ) {
push(@query, "$name=$para{$name}");
}
#various parameters
$comline = join("\&", @query);
system("/cgi/main.exe $comline");
so my question is...
how do i connect the second script to the charting program? use an LWP
package?
thanks,
pete

Not through system. You will need to use LWP to run executables through a
URL (assuming that the remote machine will let you run that program this
way). Otherwise you will need to run the program through some other, and
hopefully secure, means of executing remote programs, like ssh.
