Re: [Bug-apl] ⍝ comment ignored?

[Juergen Sauermann]

Hi,

I don't want to restart the "A Comment is a Comment" discussion, but
if I remember correctly then the argument to the )FNS command (!) is the
prefix of the function names that shall be displayed.

GNU APL is a bit lazy in commands in that it does not complain about additional
arguments but simply ignores them. So

      )fns ⍝ doesn't show SQL∆Connect

actually means

      )fns ⍝

And it shows all functions whose name begins with ⍝.
Which normally are very few, if any.

So, like it or not,

      )fns ⍝

is different from

      )fns

For example:

      )copy 5 SQL
DUMPED 2017-02-06 13:19:58 (GMT+1)
      )fns 
SQL∆Begin       SQL∆Columns     SQL∆Commit      SQL∆Connect
SQL∆Disconnect  SQL∆Exec        SQL∆Rollback    SQL∆Select
SQL∆Tables      SQL⍙metadata
      )fns SQL∆
SQL∆Begin       SQL∆Columns     SQL∆Commit      SQL∆Connect
SQL∆Disconnect  SQL∆Exec        SQL∆Rollback    SQL∆Select
SQL∆Tables
      )fns SQL⍙
SQL⍙metadata

      )fns x
      )fns ⍝
