===== CLEAR  =====

===== SYNTAX =====
     CLEAR size

==== PURPOSE ====


The ''CLEAR'' command serves two purposes: when ''CLEAR'' is executed, all numeric 
variables are initialized to zero and all strings are set to the empty string (""). 
This is especially useful at the beginning of a program to ensure that there are 
no residual values from previous executions. It can be used to resize (statically)
allocated memory for dynamic strings. This may be necessary to avoid "out of memory" 
errors when working with strings.
