Dear all,
On several occasions I have encountered the error
"D120 became negative due to too many dd120
instructions"
When compiling a pulse program which I had
written. I have previously found the immediate
cause but I seem to keep forgetting it. Recently it
occurred again and so this time I will report it to the
list so that perhaps I will remember it also :-)
The error seems to occur if the first instruction is
not immediately followed by a suitable delay.
1 ze
2 20u BLKGRAD
...
...
provokes the error while
1 ze
30m
2 20u BLKGRAD
...
...
does not.
A 30 milli-second delay is frequently used for disk
I/O. This d120 is doubtless defined in one of the
the Bruker C-Language "include" files. When I
have more time I will certainly try to determine the
underlying reason for this error.
In the mean time perhaps this mail will help some
poor pulse-programmer who is as puzzled as I was
by the message.
Sincerely,
Andy Soper||---------------------------------------------
