Hi Bill,
It works.
[temp=. '{. ~.'
{. ~.
[data=. < every 1 2 3 1 2 3
+-+-+-+-+-+-+
|1|2|3|1|2|3|
+-+-+-+-+-+-+
3 : (temp, ' y') data
+-+
|1|
+-+
Thanks. I'll use this one over my createCMD verb. ;)

I'm not sure why createcmd is needed, eg, you can just write
3 : '{. ~. y' 'aa bb cc aa bb cc aa bb'
3 : '+/ y' i. 5 5
or
cmd=. '{. ~.'
3 : (cmd, ' y') 'aa bb cc aa bb cc aa bb'
