Program Overview - Epson FX-80 User Manual

Lines 130 and 140 prepare to define 20 characters. Line 160 sets the
form length to 66 lines and fixes the Top Of Form at the current loca-
tion of the print head. It then goes to the logo routine, which starts at
line 700. The logo is called as a subroutine, one line at a time, with
these changes:
DELETE
69~
77~
RETURN
The other lines to be entered are in two long sections:
170 to 660
1299 to 1370
Enter them one at a time, replacing the corresponding lines from the
BARCHART program.
When you are finished, SAVE the program as STATEMENT, and
RUN it.
If
your output looks like Figure 19-2, let out a loud hooray;
you have just graduated with flying colors!
