Hello,
Is there a version of command line maple which runs in a
server mode? That is, it can be started up and accept input
from and return output to other applications, such as a Perl
script? None of the command line options to cmaple (in Maple 6)
suggest that this is the case, but perhaps not all options are listed.
Thanks in advance.

Yes. By default cmaple reads from standard input and writes to standard
output.
Use also -q option. We have successfully used cmaple as an engine
for over-the-web evaluation of math tests.
See also my answer on
http://www-math.math.rwth-aachen.de/MapleAnswers/735.html
which also contains a Java class to interact with Maple.
Regards,
theodore.

Hello,
Try the following example. It illustrates how to send commands from Maple to
Perl, and retrieve calculations and graphics.
#!/usr/local/bin/perl
#get the current process number
$pid = $$;
#open a connection to Maple
$maple = "| cmaple -q > maple.$pid";
$maplegif = "maplegif.$pid";
open(MAPLE, $maple) || print STDERR "Maple can't be opened!\n";
#Send commands via print
print MAPLE "evalf(Pi); \n";
print MAPLE
"interface(plotdevice=gif,plotoutput=`$maplegif`,plotoptions=`width=500,height=3
00`);\n";
print MAPLE "plot(x^2, x=-2..2);";
print MAPLE "quit;\n";
close(MAPLE);
Regards,
Nikolay Semchenok

The standard cmaple process will do this. I use one with emacs to
display help pages and execute code. You probably want to call it with
the -q option to suppress the startup messages. You also might have to
play with the interface settings to suppress prompts [I'm a little hazy
here, it's been awhile since I wrote the code].

I'm not quite sure I understand your question, but I have run cmaple in
a cgi directory from a perl script on a remote server. From my web
browser, using forms to enter data/procedures, I ran cmaple on the
server using this input and returned results that got displayed in my
browser. I set up the script to allow me to download output files as
well by clicking on a button.
If you want any more details let me know, but it was very
straightforward.

You can pipe a command into maple as grab the output as you would do with
every other command:
~ > echo -e "result:\n `echo 'int(x,x);' | maple -q`"
result:
2
1/2 x
The -q supresses the "banner" at startup.
