I just realised that
If a And b Or Not a And Not b Then
Could be simplified as:
If a=b Then

Subject: Language addition proposals
Hi all,
Having worked with and studied the REALBasic language for a couple of years
now, there are a number of functions that I found 'missing'. Please
understand me well, I have no baggage of knowledge about any other
programming language to speak of that could otherwise have generated a
'need' for these functions. The need is a purely practical one.
I did look up function names to make sure I'd name them properly.
Also, all of these functions can be performed by alternatives with relative
ease, much in the same way a '+' could be performed by using '--' (two minus
signs; thus: 1--1 equals 1+1. Try it, it works.)
In the descriptions bExp1 and bExp2 are Booleans.
NOR
Returns True if both bExp1 and bExp2 are False
Example:
If a Nor b Then
Now:
If Not a And Not b Then
XOR
Returns True if only one of bExp1 and bExp2 is False
Example:
If a XOR b Then
Now:
If Not a And b Or a And Not b Then
XNOR
Returns True if both bExp1 AND bExp2 are True or False
Example:
If a Xnor b Then
Now:
If a And b Or Not a And Not b Then
NAND
Returns True if either one, or both bExp1 and bExp2 are False
Example:
If a Nand b Then
Now:
If Not a Or Not b Then
IIF( bExp As Boolean, sText1 As String, sText2 As String ) As String
Returns sText1 if bExp is True, if false it returns sText2
Example:
Dim s As String = IIF( a, "one", "two" )
Now (short as possible):
Dim s As String
If a Then s="one" Else s="two"
Personally, I wouldn't have used an If-Then oneliner in the last example, so
my own gain is 5 lines there.
Should have alternatives for returning other datatypes as well. (Please, no
Variants to 'solve' this!)
I have more examples, but I don't think they'd get many votes. However,
these I listed here make sense, since they mean you have to type less while
maintaining readability of your code. Personally, I think they make sense,
syntaxically, logically as well as linguistically.
Yeah or nay?
