The WMI command returns 3RD8F3J GetBiosData prints what looks like two narrow hollow upright rectangles. When I mark it to copy it an extra narrow square bracket with the legs pointing to the right appears after a space while the left mouse button is down but this disappears when I release the mouse button. When saved to a variable the length is 4. for n = 0 to 7;??a.getbyte(n);next  produces the following output. 3         0         4         0         7         0         0         0 The computer is a DELL. The BIOS setup shows the following. System = OptiPlex 755 BIOS version = A22 (06/11/12) Service Tag = 3RD8F3J Express Service Code = 8185161583 Asset Tag = {none} Mervyn.
