RMKill a module ONLY if it's loaded

Hi there,

I would like to know how to kill a module (RMKill ) only if it’s loaded.
I know RMEnsure can execute a command… but only if the module is NOT loaded! I need the opposite.
Any ideas?

Surely RMkill of a module that is not loaded will just fail anyway?
Or have I not understood your question?

I don’t know anything about RISC OS’s command line interpreter/shell, but is it possible to use negation? That is, the equivalent of “if NOT ( a module is not loaded ) then do something”

Only when checking the values of variables/functions – and RMEnsure is a command, not a variable/function.

There are two obvious options that come to mind:

X RMKill FooModule

The ‘X’ command ignores any error generated by the sub-command

Set FooModule$Loaded 1
RMEnsure FooModule 0.00 Set FooModule$Loaded 0
If <FooModule$Loaded>=1 Then RMkill FooModule
Unset FooModule$Loaded

This is more long-winded, but will work on earlier OS versions (pre-3.5?) where ‘X’ isn’t available. And unlike the ‘X’ approach it will report an error if the module refuses to die.

If you can call a short BASIC program… It should be just this:

SYS "XOS_CLI", "RMKill ModName"

@All: Thanks for your fast responses, guys! This community is great indeed!
I am using “X RMKill”, which solves the situation and is very easy :)
