7.8.4.16 Programming Access to Data Tables
A data table is a memory location where data records are stored. Sometimes, the
stored data needs to be used in the CRBasic program. For example, a program
can be written to retrieve the average temperature of the last five days for further
processing. CRBasic has syntax provisions facilitating access to these table data,
or to meta data relating to the data table. Except when using the GetRecord()
instruction (
Data Table Access and Management
(p. 592)
), the syntax is entered
directly into the CRBasic program through a variable name. The general form is:
TableName.FieldName_Prc(Fieldname Index, Records Back)
Where:
•
TableName is the name of the data table.
•
FieldName is the name of the variable from which the processed value is
derived.
•
Prc is the abbreviation of the name of the data process used. See table Data
Process Abbreviations
(p. 168)
for a complete list of these abbreviations. This is
not needed for values from Status or Public tables.
