Hi John,

What is your PAGER environment set to?

    printenv PAGER

You can try unsetting it before you run NCL:

>From ksh/sh:

<pre>
   unset PAGER
</pre>

>From csh/tcsh:

<pre>
   unsetenv PAGER
</pre>

The "printVarSummary" command is working because it didn't need to
page the output to multiple pages in order to display it on your
screen.
