Hi Mila,
I've only ever used IDL5 under NT, and with 5 you only have the Developer
Enviroment, a Windows based, pointy-clicky interface (which is not bad). As
such I was unable to send text to IDL with perl by piping to an IDL process,
although you may have more luck with 4.
Alternatively if you can do what you want to do with a startup file in IDL
then you could just startup IDL with a system command such as
system('"c:\program files\idl\idl51\idlde.exe"');
Note the use of single quotes and double quotes, the latter are needed since
there is a space is the executable name.
To create a process that you can pipe (print) characters to, do something like
this:
open IDL, '|"c:\program files\idl\idl51\idlde.exe"';
print IDL "xloadct\n";
but as I said this doesn't work with windows apps, only command line (DOS)
apps - although it does start IDL up.
Finally, if you upgraded to 5, you could try using PerlScript to manipulate
IDL as an ActiveX object, although I never tried either of those things and
I've no idea how difficult/possible it would be.
Good luck,
Justin
