;                              EX.DO

;   DO files save time and avoid typing errors. You can create a 
;   series of commands which will be carried out in the sequence 
;   in which they are written in the DO file.
;  
;   DO files are written in non-document mode on a word processor
;   (such as WordStar) and executed by typing DO and the file name:
;
;   for example DO A

;   This simple example incorporates the exercises in lesson 6.
;
;   Explanatory remarks in a DO file are preceded by a semi-colon (;)

;
;   First, to copy F3 files to files starting with F4:
;
COPY F3*.* F4*.*;N 
;
;   A directory listing will show the effect of this command:
;
DIR 
;
;   Now let's see only the files that were copied: 
;
DIR F4*.* 
;
;   With the RENAME command these filenames can be changed:
;
RENAME F4*.* F5?????1.*;N 
;
;   The TYPE command will not find filenames with spaces in:
;
TYPE F5TXT  1.DAT 
;
;   An error message is displayed.
;   DIR finds all the files (including F5TXT  1.DAT):
;
DIR 
;
;   Finally to delete all files beginning with F5:
;
DELETE F5*.*;N
;
;   DIR shows the same files we started with:
;
DIR 
;
;End of EX.DO
