Thanks...
I'm running Bell Labs Plan 9 in Virtualbox. (I’m not sure how to get the
version from the os or from rc)
I copied and pasted the snip directly into a script with only that in it - same
error as before:“rc (testread): variable name not singleton!”
As for the second part - I will move that to the other thread. There are now
some things I’m exploring there with the ifs variable, (which I thought the ifs
variable was limited in plan 9 from what I read).
