##Moo
... More code
The program defines two variables named x and k.
##Foo is an entry point.
After compilation, it is possible to run this piece of code by commanding XQ ##Foo to the interpreter.
When the program starts at ##Foo, it clears the user variable x. It then iterates 11 times, incrementing x with
every iteration. Finally, x = 11.
The exit command terminates program execution.
Another code section can be executed by commanding XQ ##Moo.
Example 2:
switch (IP & 3) Select according to the two low input bits
case 1
PR=1000; If value is one...
case 2
PR=500; If value is two ...
otherwise
PR=100; Otherwise...(Last two bits are 0 or 3)
end
BG Begin motion
This example moves an axis with a step that depends in the state of the digital inputs.
5.2 Common
A user program contains lines of text code. This text must have defined syntax for the Compiler to recognize
it. This section contains some common description of a program text.
5.2.1 Line and Expression Termination
A line has the following terminators: carriage return, line feeds or their combination.
A line can contain a single expression or sequence of expressions. Sequence of expressions in the same line
can be separated with semicolon or comma (not inside round or square parentheses).
Example:
a = 3 , b = 2 , c = a + b , ** This line consists of three expressions separated with comma
a = 3 ; b = 2 ; c = a + b ; ** This line consists of three expressions separated with semicolon
a = 3 , b = 2 ; c = a + b ** This line consists of three expressions separated with comma, semicolon and
terminated with line feed
[a,b] = foo (23, c, 3.14) ** In this expression comma is not expressions separator, because it is inside
parentheses
