===== UBOUND  =====

===== SYNTAX =====
     = UBOUND( array [, dimension])

==== PURPOSE ====


The ''UBOUND'' command (short for "upper bound") is used to determine the 
highest index of an array. In other words, it tells you how far up 
the array goes.

Imagine you have a box of numbered chocolates. ''UBOUND'' tells you what 
the number of the last chocolate is. This is useful when you need to 
iterate over all the elements of an array, because it gives you the end 
point of the loop.

''UBOUND'' and ''LBOUND'' are often used together to define the bounds 
of a ''FOR'' loop, and are complementary commands: they allow you to obtain 
complete information about the structure of an array. Knowing these two 
values, you can iterate over all the elements of the array, calculate 
its total size, and perform many other operations.



==== EXAMPLE ====
    DIM a(10,20)
    PRINT UBOUND(a,1) : REM it will print 20


==== ABBREVIATION ====
   Ub
