Define Data Elements |
DATA expression[$][, ...]
Where:
|
expression[$], ... |
A series of string or numeric expressions. |
Use the DATA directive to define the values for the READ DATA directive. The values to be read can include constants, variables, and/or expressions. You can use a formatted IOList with a READ DATA statement. When PxPlus executes the READ DATA directive, it evaluates each expression in order and places its value into the corresponding variable(s) defined in the READ DATA directive.
When PxPlus progresses through reading the data, it increments an internal pointer to the next data expression. When the end of DATA statement is reached, PxPlus proceeds to the next DATA statement in the program. PxPlus returns Error #2: END-OF-FILE on read or File full on write when no further DATA statements exist in the program.
