THE PROGRAM EDITOR
------------------



SEKA PROVIDES TWO EDITORS FOR EDITING THE PROGRAM (SOURCE).THE SCREEN
EDITOR IS EASIER TO USE FOR MOST PURPOSES,AND THAT IS DESCRIBED FIRST.
FOR FUNCTIONS SUCH AS LOCATING TEXT ,USE A COMMAND DESCRIBED UNDER LINE
EDITOR.


SCREEN EDITOR
-------------
NOTE THAT ALL EDITING IS DONE IN THE SOURCE BUFFER IN MEMORY-THERE IS NO
CONCEPT OF EDITING A DISK FILE.

TYPE <ESC> IN RESPONSE TO SEKA> PROMPT,TO ENTER SCREEN EDIT MODE.
PRESSING <ESC> AT ANY TIME FROM WITHIN THE SCREEN EDITOR WILL EXIT TO
COMMAND LEVEL(THE SEKA> PROMPT)

<CTRL-O> WILL OPEN A BLANK LINE BEFORE THE CURRENT ONE.

CUT AND PASTE
IN THE SCREEN EDITOR IT IS POSSIBLE TO CUT OUT A SECTION OF TEXT,AND PASTE
IT IN ZERO OR MORE TIMES.

INITIALLY PLACE THE CURSOR AT THE BEGINNING OF THE PIECE TO CUT OUT,AND MARK
IT USING <CTRL-B>.MOVE THE CURSOR TO THE END,AND TYPE <CTRL-C> TO CUT IT
OUT.

TO PASTE,JUST TYPE <CTRL-P>.THE BLOCK LAST CUT OUT WILL BE PASTED IN AT THE
CURRENT CURSOR POSITION.

NOTE THAT LEAVING SCREEN EDIT MODE,RETURNING TO SEKA> COMMAND LEVEL,WILL
ERASE THE PASTE BUFFER.


THIS IS USEFULL FOR:
A)DELETING TEXT,JUST CUT IT OUT.NO PASTE
