     I'm getting a weird error using the BASIC (ugh!) TIMER function on
Lines: 23
Xref: mnetor comp.sys.att:1227 comp.sys.ibm.pc:7771

my 6300 (minus).  I'm calling it in a loop to control my Metrabyte data
aquisition board (which comes with an assembly language routine callable
from basic).  At seemingly random times I get values that are in error.
the values (in seconds past midnight) go greater than 86400 (the number
of seconds in a day.)
    I'm using ATT dos 3.1 and ROM BIOS 1.21 if that makes any difference.
the error occurs with GWBASIC and IBM Basic Compiler.  I haven't been able
to duplicate it on an IBM AT but maybe I just got lucky.  On my 6300 the
error occurs 1 to approx 6 times a day.
    Any suggestions?  Could I be trying to read the clock as it is being
updated?  Am I correct that this has nothing to do with the battery-clock
since the machine is running continuously?  Is there a better way to get the
"real time"?  Any ideas would be appreciated.
