    Default How many AND / OR are accepted ?

    good day ,
    I have a very simple qestion regarding the number of AND and OR can be put in the " if " control under PicbasicPro.
    Eg.: if (a>b) AND (c>d ) AND (e>f) AND (g>h) AND (i>l ) AND ( m>n) AND (o>p) THEN ....
    How many AND / OR are accepted ?
    Thanks
    Ambro

    I think that the number of Logic are limited by the two line space!

    But you can do the and Logic with nested if/then like this:

    If a>B then
    If c>d then
    If e>F then
    .
    .
    If x>z then

    Code for the Action necessary If all the ands are satisfied

    ENDIF
    .
    .
    ENDIF
    ENDIF
    ENDIF

    This type of construct is shorter in terms of ram usage and is much faster than the corresponding "line construct"
    With the same approch you can make the OR construct.

    Naturaly here the limitation is the ram size of your mcu.

    Cheers
    Al.
