Editing Line Windows
You can define subsections of the line, called line windows, on which EDIT executes all subsequent commands. In the descriptions of EDIT qualifiers, the beginning of the line always indicates the beginning of the line window.
Whenever EDIT verifies a current line, it indicates the position of the line window by displaying a > character directly beneath the line. EDIT omits the pointer if the line window begins at the start of the line.
The following commands control the position of the character pointer:
|
>
|
Moves the pointer one character to the right.
|
|
<
|
Moves the pointer one character to the left.
|
|
PR
|
Resets the pointer to the start of the line.
|
|
PA <string>
|
Moves the pointer to the first character after the specified string.
|
|
<string>
|
Moves the pointer to the first character before the specified string.
|
The following commands change the character at the current pointer, then move the pointer.
|
$
|
Makes the character at the pointer lower case, then moves the pointer one character to the right.
|
|
%
|
Makes the character at the pointer upper case, then moves the pointer one character to the right.
|
|
_
|
The _ (underscore) command deletes the character at the pointer, turning it into a space, then moves the pointer one character to the right.
|
|
#
|
Deletes the character at the pointer, then moves the rest of the line one character to the left. To delete several characters, specify a number before the #. For example, 5# deletes the next five characters in the window.
|
A combination of these commands can be used to edit a line character by character.
The following commands insert and exchange text on the current line, similar to the A, B, and E commands; however, the character pointer is moved on completion.
|
Insert <string2> after <string1>
|
A,P <string1> <string2>
|
Inserts <string2> after the first occurrence of <string1>. The pointer is then positioned after <string2>.
|

Insert <string2> before <string1>
|
B,P <string1> <string2>
|
Inserts <string2> before the first occurrence of <string1>. The pointer is then positioned after <string2>.
|
|
Exchange <string1> with <string2>
|
E,P, <string1> <string2>
|
Replaces the first occurrence of <string1> with <string2>. The pointer is then positioned after <string2>.
