once the toolkit is loaded via ')load 1 toolkit'
many variables are set to display tutorials such as:

)lib functions
--------------
prime1
pascal
observations
------------
run rc_local.sax as root if necessary
this activates the Network Shared Variable Processor (NSVP)
should say 'SVP initialization complete'
operators have higher precedence than functions
soliton APL uses xterm so the user must check things like
.Xdefaults to ensure that font settings are not over-ridden
switching from openapl to soliton apl is problematic,
it is necessary to xmodmap usapl.txt to set keyboard correctly
an array that contains enclosed elements is called a nested array
variable names can start with È
a singleton is an array containing exactly one element
