Display Control
• Change from one character set to another (base, Math, or Line Drawing).
• Create data entry forms containing protected, unprotected, and transmit-only fields.
In addition, you can do the following screen edit operations either locally or remotely:
• Delete or clear all characters from the current cursor position through the end of the
workspace.
• Delete the line containing the cursor (subsequent lines are rolled up).
• Change the characters in the line containing the cursor, from the cursor to the end of the
line, to blanks.
• Delete the character at the current cursor position (this can be done with or without
character wraparound from the next subsequent line).
• Insert a blank line immediately preceding (above) the line currently containing the cursor.
• Enable or disable Insert Character mode. When this editing mode is enabled, succeeding
characters entered through the keyboard or received from the host computer are inserted
to the left of the character at the current cursor position. This editing mode can be enabled
either with or without character wraparound to the next subsequent line.
CURSOR CONTROLS
The following topics describe how to alter the cursor/data relationship either manually (by
using the cursor control keys) or programmatically (by using escape sequences).
Home Up
Pressing the. key moves the cursor to the left margin in the top row of the screen and rolls
the text down as far as possible so that the first line in the workspace appears in the top row
of the screen.
When Format mode is enabled, t h e . key also rolls the text down as far as possible but
leaves the cursor positioned at the beginning of the first unprotected field. If no fields have
been defined, the cursor will appear at the first column of the first row on the screen.
To perform this function programmatically, use the following escape sequence:
Ec h
When Memory Lock is enabled, t h e . key rolls all not-locked text down as far as possible
below the block of locked text, instead of rolling it down till the first line of text in the
workspace appears at the top of the screen. This leaves the cursor positioned at the left
margin of the first unlocked row.
