With 4D v16 R6, splitting strings have become alot more easier with the new command Split string. To split strings into arrays, methods that spand multiple lines of code were needed in prior versions. With the new command along with the new COLLECTION TO ARRAY command also introduced in 4D v16 R6 using fewer lines of code in a more straightforward and elegant manner.

// Method: // Util_StringToArray // // Inputs: // $1 - String to split // $2 - Deliminating String // $3 - Pointer to Array to receive the results // $4 - Boolean selector, // True to ignore empty stings, // defaults to False // $5 - Boolean selector, // True to trim space characters in substrings, // defaults to False // //----------------------------------------------------------------------------------- C_TEXT($1;$input_t) C_TEXT($2;$delim_t) C_POINTER($3;$resultAT_p) C_BOOLEAN($4) C_BOOLEAN($5) C_LONGINT($options_l) C_COLLECTION($substring_c) If (Count parameters>2)    $input_t:=$1    $delim_t:=$2    $resultAT_p:=$3    $options_l:=0        If (Count parameters>3)       If($4=True)          $options_l:=sk ignore empty strings       End if       If (Count parameters>4)          If ($5=True)             $options_l:=$options_l+sk trim spaces          End if       End if    End if        $substring_c:=Split string($input_t;$delim_t;$options_l)    COLLECTION TO ARRAY($substring_c;$resultAT_p->) End if

Below is an example of using the method:

C_TEXT($test) ARRAY TEXT($myArray;0) $test:="1-2-3-4-5-6-7-" Util_StringToArray ($test;"-";->$myArray) TRACE

Below are the results:
