The Position command can be used to find the first position of a specific character in a string. Below is a method that uses the Position command to find all occurrences of a specific character in a string.

// Method name: find_ocurrences // Returns all the occurrence of the letter "i" in the string $str as well as the // number of occurrences. Search will be case sensitive. C_POINTER($1;$arrPos) C_TEXT($2;$3;$str;$search) C_LONGINT($position;$count) C_BOOLEAN($done) $arrPos:=$1 // Array with the positions of all occurrences of the character $str:=$2    // String search will be performed on $search:=$3 // Character to be searched $position:=0 $done:=False While ($done=False)   $position:=Position($search;$str;$position+1;*)   If ($position#0)     APPEND TO ARRAY($arrPos->$position)   Else     $done:=True   End if End while

This method will return an array that contains the positions of all the occurrences a letter inside a string.

Below is an example of how to call the method.

C_TEXT($str;$search) ARRAY LONGINT($arrPos;0) $str:="This is a string with many i's" $search:="i" find_occurrences (->$arrPos;$str;$search) // search for the all the positions of                                           // the letter "i" in the $str
