-----------------------------------
Defines global memory variable or array.
-----------------------------------

PUBLIC creates memory variables or arrays as global variables or global
arrays.  PUBLIC variables and arrays can be accessed and modified from
any program that you execute during the current FoxPro session.

Memory variables and arrays that are created with PUBLIC are initialized
false (.F.) except for the PUBLIC variables FOX and FOXPRO, which are
initialized true (.T.).  The PUBLIC variables FOX and FOXPRO can be used
to conditionally execute code based on the product you are running.

Any memory variable or array created in the Command window is
automatically public.

Any memory variables or arrays you wish to declare as PUBLIC must be
declared PUBLIC prior to assigning them a value.

        . If within a program you assign a value to a memory variable or array
and later declare it PUBLIC, a syntax error will be generated.

Clauses
-------

<memvar list>
        One or more memory variables to be designated as global.

[ARRAY] <array1> (<expN1>
[, <expN2>) [, <array2> (<expN3> [, <expN4>]) ...
        One or more arrays to be designated as global.  <expN1> is the number
of elements in a one-dimensional array.

        (<expN1>, <expN2>) are the number of rows and columns respectively in a
two-dimensional array.
