#11 SGL Data Byte Order

[Anonymous]

Thanks for a brilliant utility.

One comment. LabView "native" read and write VIs save
SGL numbers in Big Endian format (ie. sign byte first)
while the largefile read and write VIs save the numbers
in Little Endian format. This means that SGL data
written using a native VI can not be read correctly using
the largefile equivalent and vice versa.

Once the data is read into LabView as an SGL number it
does not appear to be possible to reverse the byte order
(byte manipulation is only possible with Unsigned Integer
data formats).

It would be very useful to have a switch in the largefile
read and write SGL VIs to select Big or Little Endian
format, although this might cause confusrion to the
uninitiated!
