OR

Syntax

Description

In BASIC all logic operators
are context sensitive. The default is to perform a bitwise operation on 32
bit numbers. So that

number1 = &H55555555

number2 = &H33333333

print HEX(number1 OR number2)

number2 = &H33333333

print HEX(number1 OR number2)

Result is 77777777. The function HEX (param) returns a string representing the hex value param.

But is the context includes a comparison then the AND
operation becomes a logical operation

`So if either of the 2 conditions are TRUE then
statement1 is executed.`

If you are going to mix logical and bitwise operators then use () in the expression to evaluate the bitwise operations first, see the example below.

Example

x=&H55

y=&H33

if (x or y)=&H77 or x<y then print "OK"

' This will print OK as X OR Y is &H77

y=&H33

if (x or y)=&H77 or x<y then print "OK"

' This will print OK as X OR Y is &H77

Differences from PBASIC

- PBASIC OR is always logical, and | is bit wise
