<h1>UCB Scheme - Frequently Asked Questions</h1>
<p>
Nov 21, 2005
</p><ol>
<li> "<i>The <b>arrow keys</b> output certain escape sequences (^[]A to ^[]D)
instead of moving the cursor." </i>
<p>STk does not support arrow keys. You can run STk from within Emacs (using,
e.g., M-x shell or M-x run-scheme) if you want to use arrow keys.</p></li>
<li> "<i>I'm trying to install the STk rpm on <b>redhat linux 7.3</b> but
when I type in the command 'rpm -i STk-4.0.1-UCB6.i386.rpm' or
'rpm -Uvh STk-4.0.1-UCB6.i386.rpm', an error message tells me that
there is a failed dependency because my system doesn't have the korn
shell running."</i>
<p>You can go ahead and run the command
'rpm --nodeps -i STk-4.0.1-UCB6.i386.rpm'.
Or you could install ksh, with the command:
'rpm -i ftp://ftp.redhat.com/pub/redhat/linux/7.3/en/os/i386/RedHat/RPMS/pdksh-5.2.14-16.i386.rpm'</p></li>
<li> "<i> The 'File Save' window and the 'envdraw' command don't work.
I'm using the STk version of scm on a <b>Windows 9x</b> system."</i>
<p>This is a known bug that we cannot fix. The Tk calls that are
needed for the 'File Save' window and the 'envdraw' command do not
work on Windows9x. They do work on WindowsNT/2000/XP.</p></li>
<li> "<i> I can't get STK to load onto my laptop with <b>Windows Me</b>.
I follow the instructions, add it to the start menu, but when I
click on the program to load it, it doesn't do anything: the cursor
goes to an hourglass to indicate action, but no window opens. What do I
do?"</i>
<p>The problem was that when you unzipped the file, it automatically saved
as C:\Program Files\STkWin32, so when you'd click on stk.exe, it would not
execute because the path was incorrect. To solve this, you just had
to drag the STk folder within STkWin32 to the Program Files folder.</p></li>
<li> "<i> I'm logged into an Instructional UNIX system from a Mac [or Linux].
I type 'stk' and I get an error that starts with:<p></p><ul>
<b>X Error of failed request: BadAtom (invalid Atom parameter)</b>
</ul></i>
<p>To correct this, use the "-Y" option with ssh, for example:
<b>ssh -l cs3 solar -X -Y</b>. This is not an bug in stk; it is
related to how openssh sends certain X calls over the encrypted channel.
</p></li></ol><p></p>

<h3>To Instructional Support:</h3>
The source for this faq.html file is
<b>/home/aa/projects/scheme/public_html/faq.html</b>.
To make it accessible from ~scheme and ~instcd, there is a hard link between
<ul>
<li>/home/aa/projects/scheme/public_html/faq.html</li>
<li>/home/aa/projects/instcd/public_html/inst-cd/source/stk/faq.html</li>
</ul>
References to it from the ~scheme and ~instcd WEB pages are relative to
one of those, ie
<ul>
<!-- Convert < to CGI-speak so it won't be interpreted as start of tag -->
<li><xmp><A HREF="../../faq.html"> under ~scheme</xmp></li>
<li><xmp><A HREF="../../source/stk/faq.html"> under ~instcd</xmp></li>
</ul>
This is to ensure that a single, current version is always accessible from
both WEB sites, and that a copy of it will always be burned into the ~instcd
ISO file when we make one.
