Re: [Bug-apl] Multiline D-functions

[Juergen Sauermann]

Hi Martin,

correct. As chapter 2.11 of apl.info says:

"GNU APL supports direct functions (aka. lambdas), but only in a rather
limited form."

One of several reasons for that is that the ISO standard describes the operation of the APL interpreter as being line-by line. You can also not have,
for example, a statement spanning several lines.

Hey

I just started to use GNU APL. It seems that D-functions are not
allowed in Dfns? I get a syntax error on something simple like

foo ← {
  42
}

As far as I understand the concept of Dfns comes from Dyalog, and here
they are allowed to span multiple lines.
