Variable Storage
Atari BASIC keeps a list of the variable names used in a program
in its variable name table. A m ax imum of 128 variable names can
be stored in the variable name table. Therefore, an Atari BASIC
program is effectively limited to a maximum of 128 variables.
These include numeric, string, and array variables. An array
variable name counts as only 1 name in the variable name table ,
regardless
of the number of elements within that array.
Every
time a new variable is entered in the imm e diate mode, that
name is added to the variable name table. In the program mode,
variables are added to the variable name table as they are
encountered in the program.
