Utility of ARRAYREAD

[Alberto]

The ARRAYWRITE command is clear to me and I have used it succesfully in a program to write to an oled display. Totaly unclear to me is the use of ARRAYREAD command. Can somebody post a snippet with a practical example on how and when to use arrayread?

Thank you so much for any help you will give me on this subject.

You can use it to parse arrays. Here is how I'm using it to parse a NMEA string from a GPS:




...

'Parsing GGA
'$GPGGA,193931.000,4600.0000,N,07100.0000,W,1,05,1 .5,212.0,M,-28.5,M,,0000*6A

ARRAYread BufferGPS, BFLN_GPS_BUF, Err_ParseNMEA, _
[wait("$GPGGA,"), str GPSTime\6, wait(","), _
str Latitude\9, wait(","), str Lat_NS\1, wait(","), _
str Longitude\10, wait(","), str Long_EW\1, wait(","), _
dec GPSFixQual, dec SatCount, str HDOP\3\","]

NMEAValid = 1

Err_ParseNMEA:
return

Thank you MichelJasmin for the useful snippet! Now it is much more clear (for me) how to use the ARRAYREAD command.
