10.9 Using the Append Operator in Field Assignments

You can append data to fields using = + (append operator) in field assignments. Use the append

operator to generate dynamic packets and avoid restating previously assigned values. For

example, if a packet variable field SomeField contains “01 02 03”, to add “04 05 06” you can

assign SomeField = +{04 05 06} ), rather than assigning SomeField = {01 02 03 04 05 06}.

Note: Do not confuse this operator with the += operator, or a parse error will be generated!

You can write the append operator as = + or =+ (without a space), but it is recommended to use

the space to avoid confusion with the += operator.

Examples

Packet BPOIE

{

ElemID : 8 = 1

ElemLen : 8

BPLen : 8

Occupancy_Bitmap : *

DevAddrList : *

}

BPOIE $Beacon3_BPOIE

BPOIE $Beacon11_BPOIE

Main

{

$Beacon3_BPOIE

{

BPLen = 16

Occupancy_Bitmap = { 00 55 55 55 01 }

DevAddrList = { 04 00 }

}

# Generate DevAddrList for Addrs 5-16 : DevAddrList = {04 00} -->

# DevAddrList = { 04 00 05 00 06 00 07 00 08 00 09 00 0A 00

# 0B 00 0C 00 0D 00 0E 00 0F 00 10 00 }

for( i=5, i<17, i++)

{

$Beacon3_BPOIE{ DevAddrList = +{ i 00 } }

}

$Beacon11_BPOIE

{

BPLen = 16

Occupancy_Bitmap = { 10 55 15 55 01 }

DevAddrList = { 03 00 }

}

# Generate DevAddrList for Addrs 4-10 and 12-16 :

# DevAddrList = {03 00} -->

# DevAddrList = { 03 00 04 00 05 00 06 00 07 00 08 00 09 00

# 0A 00 0C 00 0D 00 0E 00 0F 00 10 00 }

for(i=4, i<17, i++)

{

if (i!=11)

{

$Beacon11_BPOIE{ DevAddrList = +{ i 00 } }

}
