It is the "Variable Allocation Table" but i think this is a slang term type
of thing, referring to the Symbol Table. It is a structure in Ram that holds
address and information for every Variable on the calc, so that the calc can
keep track of where everything is. The variable names, data type, and pointer
to where it is located, is kept in each variable "entry" on the table. By the
word Allocating, i guess it means that the vars are moved around by the OS
frequently, or maybe this term VAT is used with the shells that move vars
around (relocation) and need to keep track of where they originally go, after
the shell is done running an asm program. Again, im guessing on that... =P
