Section 9. Programming
9.11 Program Access to Data Tables
CRBASIC has syntax provisions facilitating access to data in tables or
information relating to a table. 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: name of the data table
• FieldName: name of the variable from which the processed value is derived
• Prc: Abbreviation of the name of the data process used. See TABLE.
Abbreviations of Names of Data Processes p. 90 for a complete list of these
abbreviations-not needed for values from Status or Public tables.
• Fieldname Index: Array element number (optional)
• Records Back: How far back into the table to go to get the value (optional)

For instance, to access the number of watchdog errors, use the
