%Split should allow array index

Currently %Split returns an array, but it would be nice if it would allow a single index of the array to be returned directly by coding for example mystring = %Split(string: ':')(1); This avoids using a work array.

    Regarding the third issue where you want to split on a string rather than a list of characters, please open a separate Idea. As a work-around, you could use %SCANRPL to replace the separator-value in the source string with a single character such as x'00' or some other character that is guaranteed not to be in the source string.

    Some comments...

    1. Needing the first (or any other element) of the array by using a For-Each loop is not practical as you can't write an expression, or pass it as a parameter to another procedure. For example instead of DoSomething(%Split(myString: ',')(1)) one would need to write several lines of code.

    2. Fine.

    3. What you're referring to is something different. I want to split on the string specified as the second parameter for %Split, even if this parameter is more than one character, ie. the characters should not be considered as multiple different delimiters but as one single (multi-char) delimiter.

    IBM does not intend to provide a solution to this request at this time, so it is being closed.

    This requirement has several separate requests:
    1. Allow an index for %SPLIT. To avoid using a work array, you could process the output of %SPLIT using a FOR-EACH loop.
    FOR-EACH item in %split(string);
    // process item
    leave; // we only want the first item
    2. The error message RNF0625 is misleading when it says that the result of %SPLIT or %SUBARR is not an array. This aspect of the requirement is accepted, and will be tracked internally by IBM.
    3. Treat each separator separately. There is already an Idea related to this. Please consider voting for that Idea instead. ("%split() should return an empty element where a separator character follows another separator character")
