10.16 RAND Token

You can use a RAND token in places where numeric literals are used to insert pseudo-random

numbers in the range 0 to 0x7fff.

Note: By default, RAND uses a different integer seed value every time the script is compiled. You

can set the seed using the RandSeed setting (for the RandSeed setting description, see the

"Generation Setting" topic).

Example

Main

{

# The frame template 'SOME_PKT_TEMPLATE' is declared later.

Send SOME_PKT_TEMPLATE

{

Field0 = { 00 RAND RAND RAND RAND 00 } # Set random hex

# stream.

}

x = RAND # Assign a random value to the numeric variable.

}

10.17 RandStream( n ) Primitive

The RandStream( n ) primitive is a utility, based on the RAND token, that produces a random

byte stream, where n is the number of bytes in the stream.

Note: For a description of random seeding, see the Note in the "Rand Token" section

(preceding).

Example

Main

{

# The frame template 'SOME_PKT_TEMPLATE' is declared later.

Send SOME_PKT_TEMPLATE

{

Fieldof32bytes = RandStream(32) # Set a random 32-byte stream.

}
