Hmm....
Actually i didn't know all that about variable handling in the ksh, so many thanks for explaining this.
On the other hand, in ksh(88) the code works as expected: the four statements generate a table with four elements and indices 1,2,3,4. The expression ${#table[@]} evaluates to 4 and the loop works fine.
I tried this now on another machine (AIX 5.1, ML06) and there it worked to what i would have expected too.
As I have understood my ksh manual "arr[n]" not only sizes an array but also denotes a specific array element. Otherwise the expression "print - "${arr[3]}" wouldn't make sense, right?
Further, the ksh93 man page states, that ksh93 now has "associative arrays" and i don't see the difference between "arr[tommy]", "arr[willy]" and "arr[1]". Since the first two values will not (for obvious reasons) be zero-based, why has the latter one to be?

Any means of running ksh93 in a ksh88-mode?
Might sound odd, but I want/need to restrict U/Win-developed scripts to correspond to the ksh88 version on my Solaris environment(s). Thanks. (2 Replies)

Hi,
I have a script that calls an external program to perform some calculations and then I read with "grep" and "sed" values from the output files.

I have a strange problem with arrays in Perl.
That is to say, for me it is strange and perhaps there is a special reason for it that I do not know of.

This is the program, as an example:

This problem seems to be specific to ksh93.
If you run with set -x some scripts don't work properly. For example:
$ cat ksh.test2
] && print FUBAR! || print OK!
$
$ /bin/ksh93 ksh.test2
OK!
$ /bin/ksh93 -x ksh.test2

get_defined_functions
GET_DEFINED_FUNCTIONS(3) 1 GET_DEFINED_FUNCTIONS(3)
get_defined_functions - Returns an array of all defined functions
SYNOPSIS
array get_defined_functions (void )
DESCRIPTION
Gets an array of all defined functions.
RETURN VALUES
Returns a multidimensional array containing a list of all defined functions, both built-in (internal) and user-defined. The internal func-
tions will be accessible via $arr["internal"], and the user defined ones using $arr["user"] (see example below).
EXAMPLES
Example #1
get_defined_functions(3) example
<?php
function myrow($id, $data)
{
return "<tr><th>$id</th><td>$data</td></tr>
";
}
$arr = get_defined_functions();
print_r($arr);
?>
The above example will output something similar to:
Array
(
[internal] => Array
(
[0] => zend_version
[1] => func_num_args
[2] => func_get_arg
[3] => func_get_args
[4] => strlen
[5] => strcmp
[6] => strncmp
...
[750] => bcscale
[751] => bccomp
)
[user] => Array
(
[0] => myrow
)
)
