5.6 Expressions
An expression is any combination of variables and constants which is combined with operators. Oper-
ators are symbols which perform mathematical or logical operations. The types of expressions han-
dled by the MZ-800 BASIC are as follows.
Arithmetic expressions
String connective expressions
Relational expressions
Logical expressions
(1) Arithmetic expressions
An arithmetic expression consists of arithmetic operators, numeric constants, numeric variables and
numeric functions, It calculates a numeric value from an operation(s) performed by the operator. (The
numeric functions will be explained later in this chapter.)
The table below lists the arithmetic operators arranged in order of operational priority.
[ Arithmetic operator | Operation
| Example
() | Gives the highest priority to enclose operations. | (X + Y)
t Creates an exponential value XTy
- Converts the sign of a value -X
«,/ Multiplication, devision | X*Y,X/Y
+= ros subtraction Ere ee
When an arithmetic expression includes operations of the same priority, they are performed in sequence
from left to right.
(2) String connective expressions
String connective expressions are used to combine two or more data strings into a single string. A string
connective expression consists of string constants, string variables, string functions and the operator
“*4'". (The string function will be explained later in this chapter.)
Example:
“ABC” +'’DEF’’ ““ABCDEF”
ON 4B EPC! .. “ABC”
