ZBI will allow storage of up to 255 variables. If more
variables are needed, consider using arrays to store data. The base
array will take up one of the 255 variable slots, but it can be
declared to allow for many indices.
Variables can be declared explicitly or implicitly.
If a variable has not been used before, it will be declared when
used. The default value for an integer will be zero and the default
value of a string will be an empty string.
Explicit
DECLARE NUMERIC <variable_name>
DECLARE
STRING <variable_name$>
If the variable existed
before the DECLARE statement, it will be defaulted.
Implicit
LET <variable_name> = NUMERIC EXPRESSION
LET
<variable_name$> = STRING EXPRESSION
The Interpreter
is limited to 255 variables. If more variables are required, consider
using arrays.
