Scintilla-based Text Editor and Corrector
SciTECO is an interactive TECO dialect, similar to Video
TECO. It also adds features from classic TECO-11, as well as
unique new ideas.

The basic approach to text editing is both radically differ-
ent and surprisingly similar to popular editors like Vi or
EMacs. Instead of using mostly keyboard commands to modify text
in a visual manner, in SciTECO you edit a program (called
macro) using very few keyboard commands (called immediate edit-
ing commands). This program edits text for the user and is exe-
cuted immediately, as far as possible. For instance, moving the
cursor to the right can be done immediatly via the "C" command
which is a part of the editor language. The language is the ed-
itor so to speak. When you delete a character from the end of
the command line macro (called rubout), the side-effects of
that character which may be a command or part of a command, are
undone.
SciTECO can also be used as a scripting language. The fol-
lowing program calculates the value of PI:
\Un Qn"= 20Un ' 0Uh 0Uv HK
Qn< J 0Uq Qn*10/3Ui
Qi< (\+2)*10+(Qq*Qi)Ua 0L :K$ Qi*2-1Uj Qa/QjUq
Qa-(Qq*Qj)-2\ 10@I// -%i >
Qq/10Ut Qh+Qt+48Uw Qw-58"= 48Uw %v$ ' Qv"N Qv-^^0= ' QwUv
Qq-(Qt*10)Uh >
