And or not etc in Oshonsoft

[Pommie]

Hi,
I have lines like;
blah (apple OR banana OR orange OR peach)
and similarly:
blah (apple AND banana AND orange AND peach)

When using the suggestions does it matter if they are 'done' in different orders? In other words, if I first (apple OR banana) then (orange OR peach) then (res1 OR res2) or 'say' OR each fruit as I go along? Similarly for AND.
C.

I hate to bring this up as it confuses the situation. Some C code defines constants as binary then ANDs them together to pass to a function as a single byte.
E.G.

#define apple  0b1111110
#define banana 0b1111101
#define orange 0b1111011
#define peach  0b1110111

    return = somefunction(apple&pear);

Note also that C uses && and || when doing comparison operations.

Mike.

Wow.. Harsh school!!

Hi I,
It didn't help! For some things, I'm slow. I need to watch the process, then I usually get it

Hi B,
I'm dealing with [& bitwise AND] and [| bitwise OR] and Oshonsoft Simulator, which uses it's own [BASIC] syntax. I can't read [c] very well.

Hi,
I have just seen the examples of CASE and these =, <>, >, >=, <, <=. from Eric, and J, I'll have to look at them another time, but thanks.

hi C,
OSH list:
E

Dim tens As Byte
Dim units As Byte
Dim x As Byte

If tens > units Then
x = 0
Endif

If tens < units Then
x = 1
Endif

If tens <> units Then
x = 2
Endif

If tens = units Then
x = 3
Endif

If tens >= units Then
x = 4
Endif

If tens <= units Then
x = 5
Endif

If tens = > units Then 'OSH will not accept the '=' sign first
x = 6
Endif

If tens = < units Then 'OSH will not accept the '=' sign first
x = 7
Endif

Hi,
Can someone check the examples in the attachment in #27 please? I am not getting the results as shown.

Hi Eric,
My mind is so blocked with OPERATORS, that I am not seeing the wood for the trees.
Thanks for your examples. Of course, I use these all of the time

Hi,

bitwise AND
logical AND
logical NOT

I have a line with IF ((x AND y) AND (NOT (x AND z )))
How is this written in Oshonsoft?
EDITED!

I gave that answer in post #15

Hi I,
I've re-read it and now it makes more sense.
dim res1 as byte
dim res2 as byte

res2 = a and b
res 1 = a and c
res1 = not res1

if res2 and res1 then......

I have difficulty with the bottom line. Would you 'spell' it out in English please, I can't understand e,g, [if res2] If res2 what?
C.

 

[jjw]

Oshonsoft does not accept parenthesis or bitwise operators or some values in If statements.
There have to be comparisons of variables or their values.

If res2 and res1 Then
means if both res2 res1 are non zero then...

can be written in Oshonsoft:
If res2 > 0 And res2 > 0 Then

 

[Ian Rogers]

can be written in Oshonsoft:
If res2 > 0 And res2 > 0 Then

Sorry.. correct if the arguments were boolean it would work..

dim aa as byte
dim ab as byte
dim ac as byte
dim res1 as byte
dim res2 as byte

res2 = aa and ab
res 1 = aa and ac
res1 = not res1

if res2>0 and res1>0 then
   PORTB = 255
else
   PORTB = 0 
endif

end

That seems to work... when aa = 0xAB result1 is positive and result3 becomes 255... If I change aa to 0 then result1 = 0 so result3 = 0

Hi I,
Good, I get the same result.
