FUNCTION:
Deallocate the Variables & Arrays
DESCRIPTION:
The DA command frees the array and/or variable memory space. In this command, more
than one array or variable can be specified for deallocation of memories. Different
arrays and variables are separated by comma when specified in one command. The
argument * deallocates all the variables, and *[0] deallocates all the arrays.
ARGUMENTS:
DA c[0],variable-name
where
c[0] = Defined array name
variable-name = Defined variable name
* - Deallocates all the variables
*[0] - Deallocates all the arrays
