Loadrt syntax

Looking for some help at the command line using halcmd.

If I have my machine running and it has for example a minmax component loadrt'd, addf'd and net'd in use, all good named minmax.0.
And I come along at the command line and decide I want to add another minmax I can't seem to do that.

halcmd loadrt minmax names=minmax.1
Doesn't seem to do it
halcmd loadrt minmax names=test
Doesn't work.
The syntax is stumping me. If I unloadrt the existing minmax item and then reload it with a higher count, that works, but it causing the existing minmax.0 to be removed which is unpleasant.

Is there a syntax to dynamically add more of an component of a pre-existing type? I expect there is and I'm just missing some basic syntax.

Having minmax.0,minmax.1, minmax.2, minxmax.3 already existing.
halcmd loadrt minmax names=minmax.0, minmax.1, minmax.2, minmax.3, minmax.4
<commandline>:0: waitpid failed /usr/bin/rtapi_app minmax
<commandline>:0: /usr/bin/rtapi_app exited without becoming ready
<commandline>:0: insmod for minmax failed, returned -1

another try
halcmd loadrt minmax names=minmax.4
<commandline>:0: waitpid failed /usr/bin/rtapi_app minmax
<commandline>:0: /usr/bin/rtapi_app exited without becoming ready
<commandline>:0: insmod for minmax failed, returned -1

another try:
halcmd loadrt minmax names=test
<commandline>:0: waitpid failed /usr/bin/rtapi_app minmax
<commandline>:0: /usr/bin/rtapi_app exited without becoming ready
<commandline>:0: insmod for minmax failed, returned -1

How about
loadrt minmax count=4
then you have minmax.0 up to minmax.3
maybe have to addf those

Neither of the above help.

It's not specific to minmax, it's the same generic question for any component. Try it yourself, pick a componenet that you can have more of, loadrt one, addf it, do all the things you need. Then try to loadrt another.

As i remember, i had to set count= in the mymachine.hal to the proposed total amount used, also those to use later. I had the same problem with my separate pendant .hal file and postgui.hal all using toggle and toggle2nist.

loadrt minmax names=minmax.1

works for me in master. (no spaces after names=)

Thanks Andy. I believe you are correct based on my experience. It's too bad, would be nice to be able to do that. Though there are probably many other features I'd prioritize over this.
