Well, being the PICK hack I am, I couldn't help enjoying watching people
struggle with this one for a while. PICK's warped version of BASIC supports
this feature. If a variable contains a string representing the name of
a routine, one can do a call of the form:

CALL @variable(arg1, [arg2, ...])

there is no limit on the number of arguments; the routine can be any
cataloged routine (cataloged just means compiled and in a 'library').
We use it all the time for a generic window driver: It is a data driven
application that has field descritors within it that are capable of calling
any other BASIC routine. Very usefull. Indispensable, in fact. 
And yes, its possible because PICK BASIC is at least partially interpretted.

Nick.
