Initializing help system before first use

# MMSVGDISPLAY

Description | When this parameter is set to true (the default) the first call to svgrefresh starts a web browser for displaying the current graph. Changing the value of this parameter disables rendering: after a warning message is reported calls to svgrefresh have no effect and the function svgclosing always returns true. Note that setting the environment variable MMSVGDISPLAY to a non empty string has the same effect as changing this control parameter.
Type | Boolean, read/write
Values |
true | Enable rendering.
false | Disable rendering.
Default value | true
Affects routines | svgrefresh, svgclosing.
Module | mmsvg
