3 Compiler Functions
Calculating The 4 basic mathematical operations +, -, * and / can be applied to numeric constants
and numbers. Round brackets can be used, and multiplication and division come
before addition and subtraction.
Example: #RL X,Y, X+WIDTH, Y+HEIGHT
following C-style operations are also possible:
- pre/post increment and decrement: ++, --; e.g: ++a, b++, --c, d--
- shift and bit operations: , &, |, ^
- combined operators: *=, /=, +=, -=, =, &=, |=, ^=
During compiling procedure all constants are calculated and transformed to fixed
numbers.
Functions During compiling procedure all functions are calculated and transformed to fixed
numbers.
Follwing functions are available:
LO(value) returns the Low-Byte
HI(value) returns the High-Byte
MIN(value1,value2,...) returns the minimum value
MAX(value1,value2,...) returns the maximum value
AVG(value1,value2,...) returns the average value
RANDOM(min,max)
RANDOM(min,max,delta)
returns a random value from the range min..max
delta = maximum difference to the last random value
SIN(w, a) COS(w, a) TAN(w, a)
w = angle in tenth of degree
a = max. amplitude
