Hello again! Another stock market related question:
I need to merge the data of two different data files on the basis of
common dates.
QUESTION 1 -- I know that I can use a "for." loop, but I was
wondering if there was perhaps a better (perhaps faster?), more J-like
approach. The basic idea i
That is fine- it is something from "TEurbo Basic" and implemented in APL
, in a way.and is very useful, but it only works if you detect, during
coding, when to deal with a problem due, often, to coding errors. What
is needed is an interrupt outside of J (as an interrupt optio may not be
availa
I figured out how to do what I wanted:
. . .
. . .
goto_stop.
. . .
. . .
label_stop.
)
The name "stop", of course, can be any label name you wish. In
effect, this pattern can be used to "rem out" (remark out) any portion
of code that you don't want executed at a particular moment
on windows it is in bin subfolder to J installation.

Use dbstopme to stop at a specific line, see the example below. A
non-empty argument is a test, so stop if true.
Caution: if using 902 beta, get the latest beta and qt addon, as there
have been recent updates to debug.

I could have sworn that, a couple of months ago, someone posted some
code that included a "stop" command of some sort in explicit coding,
but I can't remember how it was done. I cannot find such a command
anywhere in NuVoc. Searching the wiki brought back the
"Vocabulary/JBreak" ancillary page, w
