Add new RPG operation code INZDS

Add a new operation code INZDS (or CLEAR option) to initialize a data structure with its template inz values


Use Case:

Actual you have to declare an additional "inz" data structure

dcl-ds tplStruct qualified template;
var1 char(10) inz('val1');
var2 dec(10) inz(2);
end-ds;

dcl-ds inzStruct likeds(tplStruct) inz(*likeds);
dcl-ds useStruct likeds(tplStruct) inz(*likeds);

// change values of useStruct
// reinitialize useStruct
useStruct = inzStruct;

// instead reinitialize useStruct with a new optcode
inzds useStruct;

// or with a special CLEAR option
clear *likeds useStruct;

    As discussed in the comments, this new opcode is not necessary since the RESET opcode accomplishes the same thing.

    Maybe there could be a hint/example in the RESET documentation with inz(*likeds), so you can search for it. I think as I have watched the RESET documentation I've only seen that the result field could be "name (variable or record format)" and have missed the small DS example below.

    You are right - RESET does what I want.
    Thanks for the hint.

    Ignore the Inz(*LIkeDS) bit - I see you have coded that I just missed it.

    So the simple answer is that RESET does what you want - no need for a new op-code.

    I don't understand the requirement.

    Why not add Inz(*LikeDS) to the DS definition then the template initialization will be cloned along with the field definitions? Once you have done that then the RESET op-code will do what you want

    The RESET opcode already does this.
