1.If  a=. 75 and b=. 'a='

how do I print out the following line:

a=75

In other words how do I concatenate (for purposes of display) a string  
with a value?
Perhaps this is too obvious for any of the J documents to describe but all  
I could find was the use of foreign conjunctions (1!:2) which I had a  
problem making work on J6.

2. I'd like a very simple (not the Newton-Raphson method) example that  
uses $. to do branching or looping. (I know that this may not be in the  
spirit of J, but please humor me).

3. Is there any form of editing (other than simply using ctrl-enter to  
recapture one line) on the PC?
