LOGIC FUNCTIONS
DEFINITIONS
On TDS2020F a false
flag is 0 and a true flag any other number. When a true flag is returned from a
function, it is always -1, but as an input parameter it can be any non-zero
value.
|
0<>
|
(
n - f )
|
Converts number
n into logically identical flag. Opposite of NOT .
|
|
?BIT
|
(
ca n - f )
|
Flag is true if
bit n at byte address ca is set.
|
|
AND
|
(
n1 n2 - n3 )
|
n3 is the
logical AND function of n1 and n2.
|
|
BIT
|
(
n1 - n2 )
|
n2 has one bit
set. This is bit 0 to bit 15 according the input number n1.
|
|
NOT
|
(
n - f )
|
Converts number
n into opposite flag 0 or 1. Opposite of 0<> and
identical to 0= .
|
|
OFF
|
(
aa - )
|
False (0) to
variable at aa.
|
|
ON
|
(
aa - )
|
True (-1) to
variable at aa.
|
|
ONE
|
(
ca n - )
|
Set bit n
(0 to 7) at byte address ca.
|
|
OR
|
(
n1 n2 - n3 )
|
n3 is the
logical OR function of n1 and n2.
|
|
TOGGLE
|
(
ca b - )
|
Exclusive or the
content of byte at address ca with the byte b.
|
|
WITHIN
|
(
n1 n2 n3 - f )
|
True if n1 is in
the range n2 to n3 where n2 and n3 are like the parameters of a DO loop.
|
|
XOR
|
(
n1 n2 - n3 )
|
n3 is the
logical exclusive OR of n1 and n2.
|
|
ZERO
|
(
ca n - )
|
Clear bit n
(0 to 7) at byte address ca.
