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.

1 2 ... 9 10 11 12 13 14 15 16 17 18 19 ... 123 124
