!set var_lst=<li>The variable $emph
<h4>Variables for general purposes by wims server</h4>
<ul>
$var_lst wims_exec_error$emphend is used to store error messages
of the external program called by
$(ref1)cmdlist_exec_&cmd_choose=all$(ref2)cmdlist_exec_>!exec</a>.
For this reason,
this variable will be overwritten
each time a
$emph!exec$emphend command is executed.
$var_lst wims_module_log$emphend is used for individual
module's log files: if this variable is non-empty, wims.cgi will put its
content into the module's
log file, at the
end of the process of the
user request.
$var_lst wims_version$emphend has a value preset to the
current version of the wims server
. $var_lst wims_version_date$emphend has a value preset to the
last compile
date of the server program
. $var_lst wims_site_manager$emphend contains the electronic address of the
$emph wims.conf$emphend of the site. Modules should not modify this
variable.
$var_lst wims_print_precision$emphend defines the printing precision when a
result of evaluation (via <tt>!eval</tt> or <tt>$[...]</tt>) is converted to
a character string. Default value: $emph$wims_print_precision$emphend
(may be modified in wims.conf).
$var_lst wims_warn_$emphend... is ...
$var_lst wims_compare_precision
$emphend is used to
define error tolerance
when wims compares two numerical values. Formula: <tt>!ifval a=b</tt> will
return TRUE if <center>
abs(a
-b
)*$$wims_compare_precision<
;abs(a
+b
)+1/$$wims_compare_precision. </center
> Default value: $emph$wims_compare_precision$emphend (may be modified in wims.conf).
$var_lst wims_texsize$emphend can be used to modify TeX sizes for the
module. Default value is 0 (no change). Maybe 1,2,... (increase TeX size) or
-1,-2... (decrease TeX size).
$var_lst wims_homeref_parm$emphend is reserved for future use in the command
<tt>!homeref</tt>.
$var_list wims_homeref_bgcolor$emphend is...
$var_list wims_rawmath_functions$emphend is used to tell rawmath routine that
the words contained in the variable value should be treated as function names.
These words can be separated either by white space or by comma.
$var_list wims_rawmath_variables$emphend is used to tell rawmath routine that
the words contained in the variable value should be treated as math variable
names. These words can be separated either by white space or by comma.
$var_lst wims_ref_target$emphend defines the target of the command
<tt>!href, !homeref, !form</tt>. Its value is <b>not</b> automatically
the target is the
current document
.) $var_lst wims_html_header
$emphend is the standardised html
header for all
its modules' html outputs. Its value is defined in the file
html/header.phtml. It is highly recommended that modules use this variable
to define their html headers.
$var_lst wims_expire$emphend is used to define expiration dates of the
pages sent to clients. Don't
touch it
if you don
't know what this means. $var_lst module_init_parm$emphend is...

<hr><h4>Variables reserved for dynamic insertions</h4>
!set resetyes=<br>This variable is reset to empty after a dynamic insertion.
<ul>
$var_lst ins_align$emphend defines the manner in which the inline picture
is aligned with respect to the line. Possible values: bottom, middle or top.
Default is empty (which means bottom).
$var_lst ins_attr$emphend is used to define miscallaneous attributes of a
dynamic insertion. Examples:
<pre> ins_attr = align=middle</pre>
(aligns the middle of the image with the baseline for the current
textline), or
<pre> ins_attr = ismap</pre>
(coordinates of the click will be passed back to the server; if the link
of the element is the wims server, the coordinates will be registered
under the variable $emph no_name$emphend.)
$resetyes
$var_lst ins_border$emphend is used to define border width of the html
element $emph IMG $emphend
resulted from the dynamic insertion. Its value should be a positive
number.
$resetyes
$var_lst ins_density$emphend is used to define the density of the dynamic
insertions. Default value: $emph 100x100 $emphend.
<br>
<b><font color=red>Avoid using this variable!</font></b> We are planning to
suppress it. Will be replaced by a server-managed variable.
$var_lst ins_format$emphend can be used to determine the format of the
graphics file of the dynamic insertion: its value should be either $emph
gif$emphend or $emph jpg$emphend. The default value of this variable is
$emph gif$emphend (which can be changed by modifying the file $emph
wims.conf$emphend; but such change is not recommended). <br>
Some types of dynamic insertions may not be affected by this variable.
$var_lst ins_quality$emphend is used to define quality of the graphics
convertion used in dynamic insertions. Its value should be between 0 and
100. Affects only dynamic insertions whose graphics format is jpg.
$var_lst ins_tag$emphend is used for dynamic insertions within a form.
In this case define<br>
<tt>ins_tag=form </tt>$emph name$emphend<br>
where $emph name$emphend is the name of the html element $emph IMG $emphend
within the form (optional).
$resetyes

$var_lst insdraw_size$emphend is ...

$var_lst insplot_data$emphend is ...
$var_lst insplot_font$emphend is ...
$var_lst insplot_set $emphend is ...
$var_lst insplot_split$emphend is ...
$var_lst insplot_transparent$emphend is used to define transparent color
for insertions. Default is empty (no transparency). Usual value: 255,255,255
(white is transparent).
