hi, These method is very usefull when you build software like a "lego", some pieces are polymorphic, the assignment of "source" depens of environment, params at runtime not only at compile time... the value of "soure" can be assigned from litteral, but also read from file or be the result of a text expression.
sample : if you run a software on mutiple plateform, unix and windows, UV, UD, D3, ...; to adress OS and third part software, the final syntax is different but the "main()" can call "source" with no difference, you an createa a new variation of source() with no change on the main(). sample : send a e-mail : depending of OS, smpt, relaying, it can be 20 differents method/tools to send a mail but the elements of it (from,to,subjet,body,attachment) are always the same. With the indirect call, you can define wich is the "local" method to send a mail and never touch the main(). two pence. Manu Wjhonson <wjhon...@aol.com> a écrit : I've not encountered this is my career previously, but now I'm seeing a system written almost entirely with the use of indirect calls in Universe BASIC. That is SOURCE = "*SOME.PROGRAM" ... CALL @SOURCE(INPUTS) Is there some advantage to the use of indirect calls that a system would be written entirely in this fashion? _______________________________________________ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users _______________________________________________ U2-Users mailing list U2-Users@listserver.u2ug.org http://listserver.u2ug.org/mailman/listinfo/u2-users
