Did the j602 session manager display glyph for characters above 127, eg the 133 in your example?

Actually, the characters do display properly in both the session manager and
under emacs if I set my font to Dyalog.

As I mentioned, changing "fread" to "ufread" seems to fix the problem.

This is not a bug in fixargs. The root cause is that your APL characters
are illegal in utf8. I bet those lovely characters will not display inside
J602.

turn off utf8 mode in regex by rxutf8 0
or even better, convert those APL characters to true utf8 unicode.

 Members of the Forum -

I just tracked down a bug in "fixargs.ijs" whereby it failed to fully
convert all my old code from using the "y." to "y" etc. argument
convention.

The function "fixarg" seems to fail silently for any file with double-byte
characters in it.  My subject line refers to (one place) where the problem
cropped up: I have some code converted from APL in which I've retained the
old APL code as comments.  Once again, that lovely character set causes
problems.

The root cause appears to be in the regular expression code which
apparently
doesn't play well with the double-byte characters.  It fails to match the
target string if there's such a character anywhere in the source string.

Here's a short example of the problem:

  load 'regex'
  ]str=. a.{~67 104 97 114 97 99 116 101 114 32 133 32 110 117 109 98 101
114
Character ? number

  'er' rxmatches str   NB. No result though there should be two matches.
  'er' rxmatch str
_1 0

NB. But if we replace one (double-byte flag) character by a space:
  'er' rxmatches (' ') 10}str
7 2

16 2

The good fix for this - removing the offending characters, fixing the
code,
then replacing the removed characters - appears complicated by the fact
that
the (initial) replacement in "fixarg" - the line "y=. ((sx;,2);x) rxrplc
y"
- changes the length of the string.  It's probably OK to remove but
not replace these characters but I'm not exactly sure how to identify
them.

Any ideas?

Thanks,

Devon
