            What do they mean?

The Symbolics Zetalisp character set includes the following characters not present in other Lisps (^ means control): ^] >= greater than or equal to ^\ <= less than or equal to ^Z != not equal to ^^ == equivalent to ^E not ^G pi ^L +/- plus/minus ^H lambda ^F epsilon ^W <--> left/right arrow ^X <-- left arrow ^Y --> right arrow ^A down arrow ^K up arrow ^D up caret ^_ down caret ^T forall ^U there exists ^B alpha ^C beta ^I gamma ^J delta ^O partial delta
^N infinity ^M circle + ^V circle x

Other special characters to look out for are the font-change characters, which are represented as a ^F followed by a digit or asterisk. A digit means to push font #N onto the stack; an asterisk means to pop the most recent font from the stack. You can clean up the code by replacing "^F." with "". In format statements, ^P and ^Q are used to delimit text to be printed in a particular character style.
