delphi - Bypass function "out" parameters -

some functions need variable send out value. don't need value , don't want define variable use function out parameter. this:

procedure test(out somevar: string); begin    //... end;

i want execute safely:

test;

you can create wrapper:

procedure test(); overload; var     somevar : string; begin     test(somevar); end;

note: you'll have mark other version overload, or can call wrapper other test, , remove overload.

another option: declare dummy variable somewhere (at top of unit, maybe):

var    dummystr : string;

then don't have declare new variable every time want call function.

test(dummystr);
