globalAssign -- global assignment, in function form

Usage:

globalAssign(s,v)
Inputs:
- s, a symbol, the symbol whose value is to be set
- v, a thing, the value to be assigned to s
Outputs:
- v, a thing

Description

This function mimics what happens in the interpreter when an assignment to a global variable occurs, and can be useful if the name of the symbol is not known when the code is written. If the value changes, then GlobalReleaseHook and GlobalAssignHook are called appropriately.

i1 : x = y

o1 = y

o1 : Symbol

i2 : globalAssign(x,4)

o2 = 4

i3 : x

o3 = y

o3 : Symbol

i4 : y

o4 = 4

For the programmer

The object globalAssign is a function closure.
