Hi Bob,
Thanks for the quick response and sugguestions.
For my current application it is probably the best to just write out
the arrays into a file and then read them in. However, I just wanted to
let you know that your suggestion of using the existing perl script to
write a main level IDL code with the defined arrays is also a very good
approach that I had not thought of previously.
Thanks again,
Mark

Everything limits their input buffer, or else a user could crash the
computer
if they "accidently" gave too large of an input. It is a famous bug from
the old
days. There are just better ways to handle the situation. It is like you
are
trying to put your luggage into your glove box instead of the trunk. :)

sounds good.
Or use your existing perl script to create a main level IDL code where
you define your arrays:
Pro call_full_test
a_arr =
[0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9 ,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9]
b_arr =
[0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9 ,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9]
c_arr =
[0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9 ,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9]
d_arr =
[0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9 ,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9]
e_arr =
[0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9 ,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9]
f_arr =
[0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9 ,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9]
g_arr =
[0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9 ,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9]
full_test, a_arr, b_arr, c_arr, d_arr, e_arr, f_arr , g_arr
end
Then have your script call "call_full_test"
$idl_prog_full_test = "call_full_test";
$idl_run = ".r $idl_prog_call_full_test";
$exit = "exit";
$idl_command_try_2 = "$idl_prog_call_ full_test";
Cheers,
bob

Hi Reimar,
The main question is why does IDL place a limit on the amount of array
elements being passed explicitly?
help, !version, /str
IDL> help, !version, /str
** Structure !VERSION, 8 tags, length=104, data length=100:
ARCH STRING 'x86_64'
OS STRING 'linux'
OS_FAMILY STRING 'unix'
OS_NAME STRING 'linux'
RELEASE STRING '6.2'
BUILD_DATE STRING 'Jun 20 2005'
MEMORY_BITS INT 64
FILE_OFFSET_BITS
INT 64
IDL>
As for the reason why I am passing this many elements explicitly is
that the arrays are being generated in a perl script and then passed to
an IDL program.
Below is a simple example where I am explictly passing arrays from perl
to IDL, but I run into a limitation on the amount of elements that I
can pass explicitly:
#!/usr/bin/perl -w
@a_arr =
(0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9 ,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9);
@b_arr =
(0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9 ,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9);
@c_arr =
(0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9 ,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9);
@d_arr =
(0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9 ,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9);
@e_arr =
(0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9 ,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9);
@f_arr =
(0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9 ,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9);
@g_arr =
(0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9 ,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9);
$str_a = "@a_arr"; # put array into a string with blanks
between elements
$str_a =~ s/ /','/g; # substitute
$str_a = "['".$str_a."']"; # Add IDL brackets and end quotes
$str_b = "@b_arr"; # put array into a string with blanks

$str_b =~ s/ /','/g; # substitute
$str_b = "['".$str_b."']"; # Add IDL brackets and end quotes
$str_c = "@c_arr"; # put array into a string with blanks

$str_c =~ s/ /','/g; # substitute
$str_c = "['".$str_c."']"; # Add IDL brackets and end quotes
$str_d = "@d_arr"; # put array into a string with blanks

$str_d =~ s/ /','/g; # substitute

$str_f = "@f_arr"; # put array into a string with blanks

$str_f =~ s/ /','/g; # substitute
$str_f = "['".$str_f."']"; # Add IDL brackets and end quotes
$str_g = "@g_arr"; # put array into a string with blanks

$str_g =~ s/ /','/g; # substitute
$str_g = "['".$str_g."']"; # Add IDL brackets and end quotes
# Use a here document to run IDL from linux/unix command line
$idl_prog_full_test = "full_test";
$idl_run = ".r $idl_prog_full_test";
$exit = "exit";
$idl_command_try_2 = "$idl_prog_full_test, $str_a, $str_b, $str_c,
$str_d, $str_e, $str_f, $str_g";
system("idl
<<IDL_INPUT\n$idl_run\n$idl_command_try_2\n$exit\nIDL_INPUT\n ");
exit;

I'm not clear why this is not an option. Why exactly does perl or
external array generation place this limitation on you?
-k.

Hi mark
please tell a bit more
help, !version,/str
and please explain a bit more why you are using perl for doing this.

A little known fact: if you set !EDIT_INPUT=0, the input buffer becomes
unlimited (well, memory limited). This also turns off background widget
event processing, so I wouldn't recommend it for general use.
