Let
Indicates the assignment operator.
Let variable = value
or
Let( variable1 [, variable2 [, ... ]] ) = udt
or
Operator typename.Let ( [ ByRef | ByVal ] rhs As datatype )
Command intended to help the programmer to distinguish an assignment statement (e.g. Let a = 1) from an equality test (e.g. If a = 1 then ...). As the compiler does not require it, it is usually omitted.
Let can be used as a left-hand side operator to assign the members of a user defined type to multiple variables. See Operator Let() (Assignment)
Let is used with operator overloading to refer the assignment operator. See Operator Let (Assignment)

Example
'' Compile with -lang fblite or qb
#lang "fblite"
' these two lines have the same effect:
Let x = 100
x = 100
#lang "fblite"
' these two lines have the same effect:
Let x = 100
x = 100
Dialect Differences
- The use of Let to indicate an assignment statement (Let variable = expr) is not allowed in the -lang fb dialect.
- The UDT to multi-variable Let assignment is only available in the -lang fb dialect.
- Overloading of operators is not available in the -lang qb and -lang fblite dialects.
Differences from QB
- None in the -lang fb dialect.
- The Let operator is new to FreeBASIC.
- The UDT to multi-variable Let assignment is new to FreeBASIC.
