- Hear! Hear! If I have any gripes about APL and J, it is that while
- I save time programming in them, I lose the time getting data in
- and out of them. How about the theme for APL94 being "Communicating,
- Cooperating, Competing and Coexisting with the Wider World".
-
- If we think that APL is a better mouse trap than IDL et cetera, then
- we need to be able to demonstrate the fact by grabbing IDL data sets
- and manipulating them with no fuss.

- "some innovations that I wish APL would have - extremely easy
- extensibility (.m files), and relatively easy (or at
- least possible) use of external routines (Fortran, C)".
-
- And I agree entirely. While shared variables can be used for
- this, compare the straight forward use of arrays in APL and
- the drudgery of getting a shared variable interface to work.
- Compare the difficulty of explaining to a novice reduction
- and shared variables. Not only do I want to process my Excel
- spreadsheet files with minimal fuss, I want to use IMSL
- functions with minimal fuss. In previous posts the difficulties
- of using Fortran and APL together has been discussed and it
- was concluded that using Fortran with APL is very inelegant.
- However, compared to using only Fortran, it is very elegant.
- I want it to be expedient too.
-
- Unfortunately for me, ISI has forced me to put my programming
- where my mouth is (by releasing the source to J). So I'm trying
- to hack some of the above into J.
