IF-THEN what?

[Ioannis]

Well, I am embarrased to have this asked, but maybe my coffee is not strong enough.

Isn't these two totally equivalent?

IF w1>A THEN
    IF w1<B THEN
        DO SOMETHING
    ENDIF
ENDIF

 
IF w1>A AND w1<B THEN DO SOMETHING

They do not respond as expected. I mean as the second snipet.

Both work here.

A=5:B=10:w1=7

If w1>A And w1<B 
   Debug "w1>A And w1<B"
EndIf

If w1>A 
  If w1<B 
    Debug "w1>A And w1<B" 
   EndIf
EndIf

Hi,
I tried it here as well and they both seem to do the same thing... I tried with W1 less than A, bigger than B and within the range, both routines responded in the same way, what are you getting?

[Ioannis]

Thanks for the replies. Well, I was testing a code for decoding RF remotes based on the MM53200/UM3750 or HT12 transmission protocol.

The code with the AND in the IF-THEN statements works fine.

The other with the nested IF-THENs does not.

Mystery...

Me too think that both codes are equivalent.

It reminds me some weird stuff I already experimented in the past, memory leak or whatsoever, run CCLeaner, and reboot. this should do the trick.

Out of curiosity, are you using MCSP or MPLAB?

[Ioannis]

Thanks Steve. I am using MCSP and Pickit2 with Stand Alone Driver.

You are right about the weird things. I had some in the past for un-explained reasons.

Will see.

[Ioannis]

OK. I think Steve was right.

I have this test code on a Dropbox folder in order to work on different PCs. On a freshly boot PC, guess what. Works OK!

How can a reboot make a program running as expected (or not...) ?

P.S. Maybe it is a tough one for Darrel
