A bit of an explanation to the answer

0
1
2
3

'm'(,":)"0 i.4
or
'm' ,"0 1 ": "0 i.4
will provide the same answer Raul gave.

' would be either "0 (or equivalently "+) or &.>
f'x would be either f"0 x (or equivalently f"+ x) for flat x or f&.> x
(or, equivalently f each x) for running f inside boxes of x
And I think you want 'm'&,@":"0 i.4 though there are other ways of
accomplishing that. J is not exactly equivalent to
Sorry about lack of explanation,
' is for each.
f'x is function f applied to each value of x,
!4 in k is the same as i.4 in j
monadic $ converts or casts to type char
and , is append.
("m",)'$!4, could also be {[x]"m",x}'$!4
results in,
("m0"
"m1"
"m2"
"m3")
What I'm having trouble tran
I do not know exactly what ' \: and /: do in K - if I recall
correctly, these are somewhat like rank specifications ("0) ("1 0) and
("0 1) except maybe use _ in place of 1 depending on what you want to
do, and somewhat like the use of each (&.>) and possibly boxing either
the left or right argument
My apologies if this is not where newbies email with questions.
I've become somewhat comfortable with k, in particular
' \: and /:
But I haven't exactly found how to do similar operations j.
I'm a little lost with, find the equivalent to,
("m",)'$!4
Any suggestions for transitioning from k to
