Hi folks:
Many thanks for the help so far. I seem to be making considerable progress
toward my modest objective of writing some straightforward code to manipulate
data in two-dimensional arrays. And I see written somewhere that:
"GettingHelp,........... A great manyexperienced J users monitor messages sent
to the Forum and are willing toanswer your questions on J, from the trivial to
the profound."
Well here is a question which must rank among the most trivial ever asked(!):
The documentation says it is not necessary to save your work, it is
automatically saved. My question is: When I open a new session, where should
I look to find my data (and programs?)? I have created small tables of
numerical data in both the execution window and in script files. When I open a
new session, if I ask for the data I had created in the previous session there
is, of course, no response from the script file, and the execution window seems
to start out blank. If I copy the array name from the script to the execution
window and hit ENTER it tells me: "I value error: xxx"
Similarly with short experimental functions (verbs) I have written: each time
I want to run a 'program', do I have to transfer the coding of it, and any
subroutines, from the script file to the execution file? Or is there a way to
preserve the programs so they are ready to be used again in the execution
window in a new session? Certainly moving functions from the script file to
the execution window would not be arduous. But it would not be 'user-friendly'
not to have easy access to the data arrays.
Also, as an aside, the execution file is called "Term". Is that the
abbrevation of a longer word?
I want to create some largish two-dimensional numerical arrays each of which
will take several hours to assemble, and then manipulate these data multiple
times over future sessions. So where/how do such variables get
stored/retrieved so I do not have to assemble them each time I want to
manipulate them again after starting a new session?
Thank you.
Rodney Nicholson.
