7.7.3.10 Program Access to Data Tables
A data table is a memory location wherein 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. 517) ), the syntax is entered
directly into the CRBasic program through a variable name. The general form is:
Where:
TableName.FieldName_Prc(Fieldname Index, Records Back)
• 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
Abbreviations of Names of Data Processes (p. 148) for a complete list of these
abbreviations. This is not needed for values from Status or Public tables.
• Fieldname Index is the array element number in fields that are arrays
(optional).
• Records Back is how far back into the table to go to get the value (optional).
If left blank, the most recent record is acquired.
