3.09 Instream Data


Instream data is a series of lines within a program that contain either LynPlex expressions or complete lines that may be in another language such as HTML.

A data stream starts with the word data and ends with a statement that consists solely of a delimiter. The delimiter can be any value and is specified on the data statement. Spaces surrounding the delimiter are ignored.

A data statement can be a separate command, in which case it must be immediately preceded by a label. The label will be used during processing to identify the data stream.

Alternatively, a data stream may also be started with the data keyword included in a put statement. In this case the data stream can only be processed as part of the put statement.


Each statement in a data stream may be any expression or series of expressions that would be acceptable as the source of a put statement. This can include strings, numbers, variables, functions, commas and concatenation, including at the end of the line.

Raw Data

Each line may also be considered as a complete string. This can be used for generating code in another language that does not need interpreting.

If the word asis follows the word data, everything up to the delimiter line is considered to be raw data.

Future Options

To be implemented.

  • A data stream is read only and may not be changed. It may, however, be loaded into an array using the LOAD command. The data within the array can then be modified as required.
  • A data stream may also be used as the source for a GET statement.
  • Each line in a data stream can be accessed as if it were an element of an array.
