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" |
