DATA
Syntax
DATA expr1 [,expr2]...
Description
The UniBasic DATA command places data in an input queue stored in @DATA.
ASCII character 013 (CR) delimits elements in the queue. Each subsequent INPUT
statement reads one element. @DATA is read-only. For more information about @
variables, see Appendix B, “UniBasic@variables.”
The expressions (expr1 and expr2) can be literal strings or variables. You can
continue DATA statements over several lines by placing a comma at the end of each
line to be continued.
UniData places data in the queue in order of execution of DATA commands. The
queue processes on a first-in, first-out basis. When the input queue is empty, UniData
requests input from the terminal. The input queue remains available through program
CHAIN and EXECUTE operations, but is cleared when control returns to the
UniData ECL prompt (:).
Tip: You can load inline prompts in paragraphs with the DATA command. For
instructions, see the UniData Commands Reference.
Example
In the following example, the program segment executes a DATA statement
containing variables and constants of both string and numeric types. The first value,
10, is read by a subsequent input statement and assigns the value to the variable
COUNT.
