CRBASIC EXAMPLE. Definition and Use of a Data Table
(p. 79),
data table declaration begins with the DataTable () instruction and ends with the
EndTable () instruction. Between DataTable () and EndTable () are instructions
that define what data to store and under what conditions 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.
9.7.1.1
DataTable () and EndTable () Instructions
The DataTable instruction has three parameters: a user-specified alphanumeric
name for the table (e.g., "OneMin"), a trigger condition (e.g., "True"), and the
size to make the table in RAM (e.g., auto allocated).
•
Name
-The table name can be any combination of numbers and letters up to
16 characters in length. The first character must be a letter.
