Can not get my IF THEN statement to work

[bartman]

If you really are using PicBasic and NOT PicBasic Pro then any ENDIF and ELSE statements won't work for you. Keep that in mind when writing your program. You need to work around that. Some of the solutions presented won't work "as is" for that reason.

Rhatidbwoy has the right idea in his example.

I have never been able to get an "If - Then" command to work using more that one condition in PIC Basic. That is no A and B. Only A, then another question.

If I want to test a as 10 plus b at 20 for calling x:
loop:
if a = 10 then isb
loopb:

isb:
if b = 20 then x
goto loopb

AND and OR are valid PicBasic commands used with IF/THEN and the proper syntax is "IF A=1 AND B=2 THEN" so if your's aren't working I don't think that is the reason. I'm just not good enough at reading other people's code to sort out the why.

Sorry.

shouldnt the line "if B6 = $31 and B7 < $35 then twenf" read:

if B6 = $31 and B7 < $35 then GOTO twenf ?

or is the GOTO not required when using an if statement?

[dw_pic]

To my knowledge, "with picbasic, not pro"

The picbasic compiler will see the added "goto" as a undeclared symbol and choke on it.

the action is a goto, but the syntax is

if X = true then label

The problem that I have with the statement is that when it is executed to the goto from the IF...THEN I used poke. When writing to a VAR I do not need the poke, but when I need to write to a address on the chip, per-say, that is when I would use the poke or peek. Example: POKE $86,0 for writing to the chip ;

(NOT CORRECT)
twenf:
poke B6,$32: poke B7,$35:goto cs

(CORRECT)
twenf:
B6 = $32 : B7 = $35 : goto cs

OR

twenf:
B6 = $32
B7 = $35
goto cs
