>A PChar is like a String. The diference (mainly) is that a PCHAR String is not null-terminated and a String datatype in Delphi is null-terminated and dynamicall allocate the memory. Outside Delphi, like VFP, is safe map to the local String datatype...That it, PCHAR&String are the same animal, with diferent internal manipulation that is not important outside Delphi.

But, in this case, TChar is array of individual chars, and is possible map symple to a String type, becuase in Delphi, all strings are array of char and become type compatibles (But i think that you want best a array manipulation).

That's great. I'll try it like you recommend. I was thinking I'd have to handle it like a struct. If you say the array can be passed by reference and all I need to do is DIMENSION (not declare, right?) aRetarray[1024], that's pretty simple. Thanks
