Some versions of Pascal do allow this. Hewlett Packard Pascal does for
one. It has to use a 'call' mechanism with the variable name as a
parameter. I've used this to make arrays of functions for state
machines. It is also a modular Pascal which looks surprisingly like M2
but not quite so heavily typed.  Not that this does any of us Amigans
any good though. :-(
