Re: [Bug-apl] Trace doesn't display all lines

[Juergen Sauermann]

Hi Blake,

thanks, fixed in SVN 334.

In GNU APL, pure comment lines without statements do not go into
the function body and can therefore not be traced.

I have to add, this problem with trace renders the trace facility very significantly crippled.  For example, I am trying to debug a function I am having trouble with.  Since so many lines contain branches or calls to functions that don't return values, I have no idea what is going on.

Thanks.

I checked, GNU APL also doesn't print branch lines.  IBM APL shows:

test[4] →2

in the trace (if it branched to line 2).

Thanks.

Trace should show that it executed each line even if that line doesn't produce a value.  i.e.

GNU APL:

      ∇test[⎕]∇

    ∇

[0]   test

[1]  ⍝ a comment

[2]   test2

[3]   x←4

    ∇

      ∇test2[⎕]∇

    ∇

[0]   test2

    ∇

      T∆test←⍳3

      test

test[3] 4

IBM APL 2:

      ∇TEST[⎕]∇

    ∇

[0]   TEST

[1]  ⍝ A COMMENT

[2]   TEST2

[3]   X←4

    ∇

      ∇TEST2[⎕]∇

    ∇

[0]   TEST2

      TEST

TEST[1]

TEST[2]

TEST[3] 4

Thanks.
