ENTERING AND EDITING DATA
Text entered via the keyboard or received from a host can be edited on the Ampex 230
plus terminal in a variety of contexts. In some cases the effect of editing depends on
whether or not write-protection is in effect (Section 3.4.1), whether characters you type are
inserted or replace displayed characters (Section 3.4.3.1), and on page characteristics
(Section 3.3). These differences will be noted when applicable.
3.4.1 Write-Protecting Data
Certain areas of the screen can be ^rite-protected". Write-protecting an area has basically
two purposes:
Prevent data in the area from being edited
Prevent data in the area from being sent to the host.
For example, write-protecting may be used to create on-screen forms. Standard
information on the form, such as headings (e.g., "Admission Form") and labels ("Name",
"Address", etc.), is entered into write-protected areas.
To enter data which you want to "write-protect",
1. Move the cursor to the area to be protected.
2. Press ESC ). (This signals the beginning of a protected field.) "WPP
1
(Write
Proteci) will appear on the status line.
2. Enter the desired characters, numbers, and spaces.
3. Press ESC (. (This signals the end of the protected field.) WPT disappears
from the status line.
To then protect such data from being edited (PRT will appear on the StatusLine),
enter the sequence ESC &.
To unprotect such data (so that it may be edited) (PRT will disappear from the status line),
enter the sequence ESC' (single quote).
