6 Data Pattern Declarations
Data pattern declarations declare named byte strings to use where you use byte vectors. Data
pattern declaration starts with the DataPattern keyword.
DataPattern Pattern_Name = { hex_stream }
Example
# Declare a data pattern containing the byte string:
# AA BB CC DD DD EE FF 11 22 33 44 55
DataPattern PATTERN_1 = { AA BB CC DD EE FF 11 22 33 44 55 }
6.1 Constants and Data Patterns in Declarations
You can use constants and previously defined data patterns in data pattern declarations. Place
constants and data patterns inside a
[] block. (You can omit a [] block for constant insertion,
but for code clarity it is recommended that you use a [] block.)
Note: When inserting constants into a data pattern, the script parser uses only the least
significant byte of the constant. For example, if constant 0xAABBCCDD is inserted, only the
0xDD is put into the data pattern.
Examples
Const MY_CONST = 0xCC
Const "MY CONST" = 0xDD
# Declare a data pattern containing the byte string:
# AA AA BB BB CC CC DD DD
DataPattern PATTERN_1 = { AA AA BB BB [MY_CONST] CC DD ["MY CONST"] }
# Declare a data pattern containing the byte string:
# 11 AA AA BB BB CC CC DD DD 88
DataPattern PATTERN_2 = { 11 [ PATTERN_1 ] 88 }
6.2 Leading Zeroes
For bytes less than 0x10, it is not necessary to add a leading 0.
Example
DataPattern PATTERN_4 = { B B 6 B B } # Is the same as 0B 0B 06 0B 0B.
