Editing a Procedure
In chapter 5, you learned how to enter the edit mode to insert a procedure
and execute the procedure at the S4B> prompt. After you read this chapter,
you should be able to use all editing commands available with the
1775-S4B scanner.
In chapter 5, we created a procedure called @TEST1 and executed it. Now
suppose you want to change the procedure. This section discusses editing a
simple procedure. If you are comfortable with the procedure concept, you
can move on to the next section (section 7.2) of this chapter.
Our procedure called @TEST1 from chapter 5 contains the following
lines:
P ‘PRINTING ON THE’
P ‘SCREEN’
Let’s change the procedure. Type:
S4B> ED @TESTI [ENTER]
This time, the CRT displays the lines:
P ‘PRINTING ON THE’
*
Type the line:
C/PRINTING/PRINT OUT/ [ENTER]
This instruction tells the 1775-S4B scanner to change PRINTING from the
procedure text to PRINT OUT.
So, the 1775-S4B scanner responds with the line:
P ‘PRINT OUT ON THE’
*
Now press [ENTER].
