Text Editor

The CAS text editor is a full screen editor that can be included in any NCL application, providing the user with comprehensive editing facilities for up to 32767 lines of text (each of up to 256 characters in length).

• Standard text manipulation facilities are provided via line commands: insert, delete, move, copy, repeat, queue, text split, text flow, and text entry. These are supported singly and as block commands.
• Scrolling functions are supported (FORWARD, BACKWARD, LEFT, and RIGHT), including the ability to specify scroll amounts.
• The ability to find occurrences of a text string is supported, as well as the ability to change one or all occurrences of a nominated text string.
• The ability to position the text on a given line number is also supported.

You can provide text editing facilities from your application by invoking the text editor through the CAS API and passing the text to be edited. The edited text is returned to the calling procedure.
