Assign values to Variables

Values are assigned to variables creating an expression as follows: the variable is on the left side of the expression and the value you want to assign to the variable is on the right.

For example:

Dim B As Long

B = 200

Usually equal sign (=) is used for variable assignment operation like:

Counter = Counter + 1

thinBasic support also some pre-assignment operators very useful in many cases. Such operators are also called compound operators

For example the previous example can be reduced to:

Counter += 1

In this case thinBasic sum 1 to the current value of Counter variable.

The following tables summarize all the supported assignment operators.

Numeric assignments

Method	Description	Example	Equal to
=	Assign right expression to a variable	Counter = Idx
+=	Add right expression to variable before assigning result back to variable	Counter += Idx	Counter = Counter + Idx
-=	Subtract right expression from variable before assigning result back to variable	Counter -= Idx	Counter = Counter - Idx
*=	Multiply variable value to right expression before assigning result back to variable	Counter *= Idx	Counter = Counter * Idx
/=	Divide (floating point version) variable by right expression before assigning result back to variable	Counter /= Idx	Counter = Counter / Idx
\=	Divide (integer version) variable by right expression before assigning result back to variable	Counter \= Idx	Counter = Counter \ Idx

String assignments

Method	Description	Example	Equal to
=	Assign right expression to a variable	MyString = "ABC"
+=	Add variable value to right expression before assigning result back to variable	MyString += "ABC"	MyString = MyString & "ABC"
&=	Add variable value to right expression before assigning result back to variable	MyString &= "ABC"	MyString = MyString & "ABC"
.=	Add variable value to right expression before assigning result back to variable	MyString .= "ABC"	MyString = MyString & "ABC"
