Read/Write Block
Description
The Writeln (for Write Line) command is used to place into console objects that display text specific content under program control. Prompter, Text, Editor, and List objects have Writeln commands. The Writeln block is distinctive in that the parameters written can be modified. These modifications are made by right clicking the Writeln block to produce a local menu which allows adding or deleting various fields for different types of information. For the ongoing display of status information the Show Event is more convenient to use.
When a project is first started the only blocks shown are for the Prompter which is predefined. As Text, Editor, And List objects are added to the project the Read/Write block list grows showing blocks for the added objects
