===== LBOUND  =====

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

==== PURPOSE ====


The ''LBOUND'' command (short for "lower bound") is used to determine the
lowest index of an array. In other words, it tells you where the count 
of elements in an array begins.

Imagine an array as a cabinet with many numbered drawers. ''LBOUND'' tells you 
what the number of the first drawer is. This is useful when you need to 
iterate through all the elements of an array, because it gives you the 
starting point of the loop.

If you have an array with multiple dimensions, you can specify the dimension 
for which you want to find the lower bound:

''LBOUND'' is essential when you write ''FOR'' loops to iterate through all 
the elements of an array. It allows you to set the initial value of the loop 
counter correctly. 



==== EXAMPLE ====
    DIM a(10,20)
    PRINT LBOUND(a) : REM it will print 0


==== ABBREVIATION ====
   Lb
