4.4.1 DataTable() and EndTable()

As already shown, data table declartion begins with the DataTable() instruction

and ends with the EndTable instruction.

DataTable(Table_Indoor,True,-1)

...

EndTable

Between these instructions that deﬁne what data are to store and under what con-

ditions data are stored. A data table must be called by the CRBASIC program for

data storage processing to occur. Typically, data tables are called by the CallTable()

instruction once each scan in the main program.

The DataTable instruction has three parameters:

• Name - name of data table up to 20 characters

• TrigVar - trigger conditions true or false

• Size - table size is set to a ﬁxed number of records or to autoallocate function

In that case the table name is Table_Indoor with a trigger variabel set to true to

run the table and a size set to automatically allocated memory limit by using the

expression -1.

4.4.2 DataInterval()

DataInterval() sets the period in which data are stored. It has four parameters:

• TintInt - time into interval for oﬀest

• Interval - how often data will be stored

• Units - specify units on which the TintInt and Interval argument will be based

• Lapses - number of lapses or gaps in the interval to track
