command arpios is unrecognized r(199);

[DY Kim]

I installed the arpois command for use. But, after executing my code, arpios sdm viocrim q23, r ar(1), I received the message: "command arpios is unrecognized
r(199);" Any advice would be appreciated.

you don't say anything about how or where you installed it - it needs to be somewhere on the "adopt" - see
