By reading the autodocs.

Something like this might work:

#BUFSIZE=256
Dim buff.b(#BUFSIZE) ; some buffer memory for the variable to be stored in
varname$="IAMSTUPID" ; better to have a variable for the name
reslen.l=GetVar_(&varname$, &buff(0), #BUFSIZE, 0)
If reslen=-1
If IoErr_=#ERROR_OBJECT_NOT_FOUND
NPrint "Variable not set"
EndIf
Else
NPrint varname$," = ",Peek$(&buff(0))
EndIf

Needing someone is like needing a parachute. If they aren't there the
first time you need them, chances are you won't be needing them again.
