Operator Operation Example
NOT Logical negation NOT (A% = B%)
AND Logical and (A% = B%) AND (C% =
D%)
OR Inclusive or (A% = B%) OR (C% = D%)
XOR Exclusive or (A% = B%) XOR (C% =
D%)
2.4 Operator Precedence
The precedence of BASIC operators affects the evaluation of operands in
expressions. Expressions with higher precedence operators are evaluated
first. Precedence of BASIC operators is listed below in the order of
precedence from highest to lowest.
Order of Precedence Type of Operation symbol
Highest Arithmetic ^
↓ Arithmetic *, /, MOD
↓ Arithmetic +, -
↓ Relational =, <>, >, <, >=, <=
↓ Logical NOT, AND, OR,
XOR
Lowest Assignment =
2.5 Labels
Line labels are used to represent some special lines in the BASIC program.
They can be either integer numbers or character strings.
 A valid integer number for the line label is in the range from 1 to
65279.
 A character string label can have up to 255 characters (if the string
label has more than 255 characters, error can be it cannot be
anticipated).
A character string label that precedes a program line must have a colon
between the label and the program line, but it is not necessary for an
integer label.
