Quetions on gettoken and strpos.

[neutrox]

a. How do I get the first and the last strings' position using sc stringpos, if a string occurs in a sequence?

b. How can I get entire blocks of repeated strings out of a variable? The following script is an attempt and I need to split those blocks ("1", "2 2", "3 3 3" and so on).

Code: Select all

// step;
   $max = "12";
   $sep = " ";
   $list = "";
   $first= "";
   $loop = 1;

   WHILE ($loop <= $max) {
// step;
                         $play = strrepeat("$loop ", $loop);
                         $first= "$first" . "$play";
                         $loop++;
                          }

   $input = $first;

   $sort = formatlist($input, se, "$sep");
   $sort = "$sep" . "$sort" . "$sep";
   $sort = trim($sort, " ");

      $uni = formatlist($input, sed, "$sep");

   foreach ($tk, $uni, $sep) {
///////////////////////////////////////////////
 step; // step here so you'll see what's needed
///////////////////////////////////////////////
   $cnt = gettoken($sort, count, " $tk ");
   $list = "$list" . "$tk = $cnt<crlf>";

                             }
  text "$list";

a. How do I get the first and the last strings' position using sc stringpos,

Help > strpos()
start: Negative start positions are supported to begin searching from the start position leftwards.

b. How can I get entire blocks of repeated strings out of a variable?

Don't understand right now (not that much time to get it).

a. completely overlooked the help note on negative start pos. Even tried the 'reverse strings' trick but of course to no avail. So thanks, as

b. no prob, now I have it done.
