Building Structs in FORTH20XX

Newer (> 2012) versions of FORTH allow you to create struct datatypes in a similar fashion to C.

\ Define a structure named point
   FIELD: ->x
   FIELD: ->y

\ Create a new point named vertex
variable vertex point

\ set the x value of vertex to 128
128 vertex ->x !

\ Push the value of vertex's x value onto the stack
vertex ->x @

\ show the results
." The value of x in variable `vertex` is: " dup . cr
