VARIABLES DESCRIPTION |
RGPRMPT |
Input |
If numeric, its absolute value is the index of the
message in the EXTENSIBLE EDITOR MESSAGE file. If zero or null, causes the
default information text to be displayed (see the INFORMATION TEXT field
description in section 1.1). If a negative number, indicates that this is an
error message and causes the editor to sound the bell and clear the iteration
counter. Otherwise, is the actual text of the message to be displayed. In
any case, the text may contain "|"-delimited replaceable parameters.
|
RGLEN |
Input |
If nonzero, the editor awaits user input of up to
RGLEN characters. If not specified, defaults to the screen width less the
length of the message (prompt). If zero, the editor does not request user
input (i.e., it only displays the message). How the editor behaves once the
specified input length is reached depends upon the setting of the RGFLG
argument (see the "1", "H", and "T" flags).

VARIABLES DESCRIPTION |
RGR |
Input |
The line number to move to.
|
RGC |
Input |
The column position to move to.

|
UPDATE |
Update changes made to the current line. For
efficiency, the editor buffers changes made to the current line in the
variable RGLN. Whenever the current line changes or a subroutine needs to
directly access the buffer, the editor writes the current value of RGLN back
to the buffer. Therefore, you should make changes directly to RGLN when
modifying the current line and should make a call to UPDATERGED2 before
directly accessing the edit buffer.
