Here is an example how to use a collection of a few J statements to
make a simple analysis
---------------- put these lines into an ijs and execute one by one using ctrl+r
a=.'abcd etc ',CRLF,' 1 2 3 4 5 ',CRLF,'jhfakjhf
idwhfakdhsfkhaiweuhfiwhf',CRLF,' line 4'
NB. a is something you have read in using something like fread
$a
a. i. a
a
CR = a
I. CR = a
10 {. 13}. a
a. i. 10 {. 13}. a
10 {. 13}. a
NB. mark the lines below and send them over with ctrl+e
f=: 4 : 0
smoutput 'parts of a'
smoutput x {. y}. a
smoutput 'parts of a using a.'
smoutput a. i. 10 {. 13}. a
)
10 f 13
