Doc Update
The following error is not listed in the CZ documentation. As an unsigned
number, it's value is 65533:
ERR_UNEXPECTED_EOF =-3 ;unexpect EOF (actual read <> bytes asked)
This would indicate a corrupt file, generally a DBF problem. See the Bullet
conference message base under "ERROR -3" for more information.

Doc Update
The following anomoly occurs when stepping through BASIC code in the QB, QBX,
or VBDOS enviroment:
.Occasionally get total mixup/overwrite of VB source code when "stepping"
.through the code as check/debug.
This is because the VBDOS environment moves memory whenever it wants to
(when it has control, such as after each time you step). If memory is
moved between the assignment of VARSEG/VARPTR (AP.recPtrSeg = VARSEG(dataRec),
for example), then that assignment is no longer valid. Do not "step" through
code that makes assignments and then calls Bullet. Once you use VARSEG/VARPTR,
and up through the use of that by the Bullet call (call BULLET(AP)), do not
allow the interpreter to take control. This is easily accomplished by setting
a breakpoint AFTER the Bullet call. This applies to QB and QBX, as well.
