Iteration variable in module vector index in INI file

[Qutab Qazi]

Hi,

How can I use iteration variable as an index range in INI file for a module vector.

For example I want to write:

**.numHosts = ${num = 200}
**.node[0..${num}].distance = 25

but this doesn't work. Is it possible to do that?

A similar question was asked here with no answer. https://groups.google.com/forum/#!newtopic/omnetpp/omnetpp/VkoIiAbUotk

Thanks.

So you want to iterate of the number of node (from 1 to 200) and each node shall have the distance of 25, correct?

**.numHosts = ${1..200, step 1}
**.node[*].distance = 25

Sorry if I wasn't clear. I know it can be done this way. That was just an example. Eventually, I want to do something like this:

**.numHosts = ${num = 200}

**.node[0..${num}/2].distance = 25
**.node[${num}/2..].distance = 50


So based on the index values I want to have different distances assigned to them. Hope it's clear now. Thanks for replying.

**.numHosts = ${num = 1..200}
**.node[0..($num/2)].distance = 25
**.node[($num/2)..$num].distance = 50

It doesn't work for me. Correct values are not being assigned to paramters this way. Testing with Omnet++ 4.3.1.

Thanks.

Seems like an iteration inside the node parentheses (left of the equal sign) is not possible.

Maybe you can
(a) rework your condition (distance depending on the node number) into a constrained expression (https://omnetpp.org/doc/omnetpp/manual/usman.html#sec346)
or
(b) define your distance parameter otherwise, maybe let it be drawn randomly between both values, 25 and 50

Can I write it like this:

*.Node[0..30].udpApp[*].typename = "UDPBasicApp"

*.Node[32..99].udpApp[*].typename = "UDPBasicApp"

*.Node[31].udpApp[*].typename = "UDPSink"
