Problem using Else

[sayzer]

can I put a pause in for debounce?
IF i=%00000001 THEN
HIGH 1
pause 50
ELSE
LOW 1
ENDIF

debounce?

IF i=%00000001 THEN

 WHILE i=%00000001
  PAUSE 50 
 WEND

 HIGH 1

ELSE

 LOW 1

ENDIF

I have tried the:
IF i=%00000001 THEN

WHILE i=%00000001
PAUSE 50
WEND

HIGH 1

ELSE

LOW 1

ENDIF

using this on four outputs my program does nothing with these four. If I take out the while statement and use the :
If i=%00000001 THEN
HIGH 1
ELSE
LOW 1
ENDIF
then my outputs for these four comes on and stays on, forever.
I been experimenting with SELECT CASE and what I am trying to accomplish is if I am pressing the button on the transmitter, the output selected comes on and stays on until I release the button instead of cycling on/off. So here is my latest rx version which does nothing, what am I doing wrong?

One more thing when I copy and paste my code to this forum everything becomes lower case. I have been reminded as a courtesy of DEFINE OSC 4 just wanted to let ya'll know
why everything appears in the lower case. Many Thanks

FineLine Viewer was created to sort out the if - endif statements by drawing brackets between the if and endif's.

the ".TXT" to remove.

Order of operations, I dunno maybe the compiler sorts this out, but . . . logic dictates, cmcon goes before anything portA, then tris registers dictate input or output, then port dictates hi or low status. Unless you are writing this for a basic stamp, why INCLUDE "bs2defs.bas" I would and always do use INCLUDE "MODEDEFS.BAS", as I haven't the foggiest as to what makes a stamp tick. Now having said this , someone will explain to me why I am all wrong

Ok, I am seeing some light, hopefully it isn't attached to a train. Thanks for pointing out the CASE ELSE, never thought about that. I started with sample code from RENTRON's site and that why I had INCLUDE "bs2defs.bas" up there, and the CMCON=%00000111 never saw exactly where that should be placed in the manual. One thing is for certain I have learned a lot from this forum. And thanks for the FINE LINE link.

I still have a problem with:
'This will do nothing

IF mydata1=%01011001 THEN
WHILE mydata1=%01011001
pause 50 ' pause for debounce
WEND
HIGH 1
ELSE
LOW !
ENDIF

or
'This works, to turn on but will not turn off

IF mydata1=%01011001 THEN
HIGH 1
ELSE
LOW !
ENDIF

Thanks again

Is there another "half" to this code, that is sending data? I ask because I want to try it out and am too lazy to write code to test it

[tazntex]

Here is the entire code with the WHILE WEND example I was trying to use for a debounce.

Please ignore what should be upper case because when I copy and paste it changes back to lower case.

For one thing, you've got more than one CASE ELSE inside the SELECT CASE block.
Check your manual...
