IF...THEN won't let numbers to be summed

[sougata]

Hi,

IF MEM_1 = 2 THEN SPEED = 1 : GOSUB SOMETHING

is equivalent to

IF MEM_1 = 2 THEN SPEED = 1
GOSUB SOMETHING

or

IF MEM_1 = 2 THEN
SPEED = 1
ENDIF
GOSUB SOMETHING

This is weird. The email message when sougata posted said

Hi,

A colon separated mulitple statement will always compile so


Code:
---------
IF MEM_1 = 2 THEN SPEED = 1 : GOSUB SOMETHING
---------
is equivalent to

Code:
---------
IF MEM_1 = 2 THEN SPEED = 1
GOSUB SOMETHING
---------
or

Code:
---------
IF MEM_1 = 2 THEN
SPEED = 1
ENDIF
GOSUB SOMETHING
---------
So if you really want to execute multiple command based on a conditions then *ENDIF*
is the way.

But the forum does not have the whole message. I am on a windows machine today so maybe...

Hi,

I wrote the original thread counting on my past experience but then again I didn't try out flotul's structure. May be I will trying peeping the compiled hex and find out if it does carry out a conditional check on ":"So did not want to confuse readers and edited. Your windows is working fine as the doors

A little suggestion:

What about a Pause or a kind of bounce killing?
Something like,

IF MEM_l = 2  THEN 
   WHILE MEM_l = 2 : WEND
   speed = speed + 1
ENDIF

OR
IF MEM_l = 2  THEN 
   PAUSE 100
   speed = speed + 1
ENDIF

Speed increases so fast that it goes crazy!

The manual and Flotu imply that:

if mem_l = 2  then speed = speed + 1 : gosub game_speed

is equivalent to

if mem_l = 2  then 
	speed = speed + 1 
	gosub game_speed
endif

Flotu,

does pbtn = 9 if no button is pushed? If it does then your code is doing what you told it to do - update speed each time through the loop while waiting for the button to be pushed whenever mem_1 is 2,3,4, or 5. See below

MAIN:
    gosub READ_BTNS
    if pbtn < 4 and Ctr_L <= mem_l then
      'lots of stuff here removed for readability (see his  post #1)
    endif

  if mem_l = 2  then speed = speed + 1 : gosub game_speed
  if mem_l = 3  then speed = speed + 1 : gosub game_speed
  if mem_l = 4  then speed = speed + 1 : gosub game_speed
  if mem_l = 5  then speed = speed + 1 : gosub game_speed

    value = value + 1           'To change the "seed" for random #
    Goto MAIN
    end

Thank you for all your remarks.

The END statement was there only for testing purpose; I'm going to remove it.

Yes, Pbtn=9 if no button is pressed.

Well Paul, I think you have found the problem.

Regarding the "IF xxxx THEN yyyy : zzzz", I thought that the "zzzz" would be executed ONLY when the IF statement is true. This is why I wrote it after each IF statement (didn't check this out now - will do this in a few minutes).

I'll come back asap.

I moved my four IF statements to the "correct place" in my loop and everything goes fine now.

I admit, while searching for hours in the wrong direction, I've lost the overview of the program's cycle.

So let me thank all of you one more time.

I'm finishing some cleanups and port it to a PIC12F683 (it's my first SMD project...).

Finally, I'll end this thread by attaching the ultimate code.
