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
"Status.WatchDogCnt," where "Status" is the table name, and "WatchDogCnt"
is the field name.
