 ## To build:
 
-        make all
+```sh
+make all
+```
 
 ## To run:
 
-	./ant some_file
+```sh
+./ant some_file
+```
 
 NOTE: the file must already exist and not specifying any arg will make the
 program exit without doing anything.
 
 ## Try:

-newline or the end of file.  Carriage return is mapped to newline

-Non-printable characters may have unpredictable results depending

 ### ABOUT THIS ENTRY:
 
-The BUF size should be set at compile time to 32767.  This value
-was used because the Sozobon C compiler for the Atari ST has 16 
-bit ints and a limit on the size of arrays & structures of 32k.  
-Also the WatCom C compiler for the PC also has 16 bits ints.  On 
-machines that have 32 bit ints (most unix boxes), a larger value 
-for BUF could be used.

-It is recommend that compact memory model be used on PC class
-machines.  Small memory model may work too provided BUF is not
-too large.

-Note that '\f' (formfeed) was used to exit insert mode because
-K&R C had no escape constant for the escape-key.

 My goals for this project were to learn and experiment with the 
 Buffer Gap Scheme [Fin80][net90], write a useful and *portable* 
-programme, and meet the requirements of the IOCCC.  I initially

 from a previous year, however this was not as portable as using a
-CURSES library with TERMINFO/TERMCAP support.

-I plan to post followups such as unobfuscated versions and bugs
-fixes to comp.editors.  Reposts of the editor.101, gap.doc, and
-editor.102 can be found in the same group every so often.
