Any expression that evaluates to true or false. |
The one line version of IF can be used :
IF expression THEN statement [ ELSE statement ]
The use of [ELSE] is optional.
Tests like IF THEN can also be used with bits and bit indexes.
IF var.bit = 1 THEN
^--- bit is a variable or numeric constant in the range from 0-255
You can use OR or AND to test on multiple conditions. The conditions are evaluated from left to right.
IF A=1 OR A=2 OR A=3 OR B>10 THEN
IF A=1 AND A>3 THEN
Dim Var As Byte, Idx As Byte
Var = 255
Idx = 1
If Var.idx = 1 Then
Print "Bit 1 is 1"
EndIf
