Generation settings specified outside the generation procedures are set before the first script generation instruction is executed, no matter where they appear in the script. The two examples below are equivalent.
Example 1
# Set a setting before the first instruction is executed.
SetPktDelay = 20
Main
{
# Some generation instructions
}
Example 2
# Set a setting before the first instruction is executed.
Main
{
# Some generation instructions
}
# Set before the first instruction is executed,
# though the Set line is below the instruction in the script.
SetPktDelay = 12
