Definitions
Chain Definition:
 Without any parameters, the chain is sent once.
 With “Repeat” and “Idle” parameters, the chain is sent N times and then nothing
is sent (idle) M times. “Repeat” and “Idle” are optional.
Frame Definition
 Without any parameters, send the frame based in default values.
 With “RunningDisp” ON, send the frames based on default values and insert a
running disparity error.
 With parameters overriding or adding to a template frame, with or without injec‐
tion of an overriding or adding to a template frame, with or without injection of
running disparity error.
Field Variable Declarations
You can declare a variable (var_name) as a frame of type (frame_type):
$var_name = frame_type
Note: Frame variables can be declared/re‐declared and used many times.
Changing Frame Fields
You can change some fields in a frame variable.
Change var_name { field_name = value }
Preprocessor Integer Arithmetic
You can declare DWORD variables, make arithmetic operations, and use them in field and
parameters assignments.
Note: Arithmetic expressions are allowed only in numeric variable assignments.
Examples:
Legal Operations
x = 2
y = ( z = 12 ) + ( SOME_DEC_DATA + 36 ) / 8
z = 0x1 << 5
s = "Some Hex Data" # constant may be used in operations
x++
y--
z += ( x + y )
x = ( ( y & 0xFF ) >> 5 ) / 12
SOF ( Repeat = x, Idle = y )
