I'm having a coupla problems with perl RT/AIX 2.2.1. Perl 3.0 is the
first version I've used so I know not if this is new:
sanders:pts0 % perl -v
$Header: perly.c,v 3.0.1.2 89/11/17 15:34:42 lwall Locked $
Patch level: 6
1) The complete.pl that comes with perl reads:
...
sub Complete {
local ($prompt) = shift (@_);
local ($c, $cmp, $l, $r, $ret, $return, $test, $x);
@_ = sort @_;
...
However the "@_ = sort @_;" seems to nuke the @_ array, leaving
it null. I worked around this by simply changing all @_ references
in the sub to @x and that works great. Bug or feature?
2) When I do a "make test" various tests fail:
cmd.subval, op.dbm, op.index, op.mkdir, op.pack,
op.read, op.sort, op.substr, op.vec
like:
sanders:pts0 % perl cmd.subval
syntax error in file cmd.subval at line 91, next 2 tokens ");"
Execution aborted due to compilation errors.
I found that line 91:
return (1,2,3);
when changed to:
return(1,2,3); # no space after keyword
works DFK.
This is also true for the other tests mostly print statements.
Again, bug or feature that you cannot have a space after a keyword?

I traced this problem down from op.sprintf into the %c function in
sprintf. Anyone else having this problem????
script:
#!/usr/bin/perl
$x = sprintf("%c",65);
if ($x eq 'A') {print "ok 1\n";}
else {print "not ok 1 '$x'\n";}
for ($i=0;$i<length($x);$i++) {
$y = substr($x,$i,1);
printf("\t" . '%2d("%s") ',ord($y),$y);
}
print "\n";
output:
not ok 1 'A'
0("") 0("") 0("") 0("") 0("")
. . . [several more lines of nulls] . . .
0("") 0("") 0("") 0("") 0("")
65("A")
---------- ALSO -----------
As a side note I'm also having problems with op.stat:
if (-l 'perl') {print "ok 25\n";} else {print "not ok 25\n";}

The problem was part of patch2 didn't get applied correctly to my source. I seem to have everything working now, thanks ronald -- sanders -- sanders Reply-To: cs.utexas.edu!ibmaus!auschs!sanders.austin.ibm.com!sanders Thought should exist outside any governmental framework.

Bug. In perl 3.0 the @_ array was made to pass items in by reference,
so it's not a "real" array in some senses. The code for assignment
should make it into a real array, but it doesn't (yet).

A compiler problem. Try defining CRIPPLED_CC, which turns some complicated
macros into subroutines. If that doesn't work, turn off your optimizer for
at least toke.c, maybe for everything.
