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.

numeric but the expression on the
right-hand side is a string, or vice
versa.
