Syntax:

Syntax 1:

[LET] stringvariable = stringexpression

Syntax 2:

[LET] numericvariable = numericexpression

Description:

LET assigns a value of expression on the right-hand side to a variable on the left-

hand side.

• In a numeric data assignment, the assignment statement automatically converts

an integer value to a real value. In the type conversion from a real value to an

integer value, it rounds off the fractional part.

• Keyword LET can be omitted since the equal sign is all that is required to assign

a value.

• The data type of a variable and an expression must correspond.
