Ticket Program Description
We do not attempt a complete explanation of the program here.
That's what the rest of the manual is all about. But we do provide a
cursory, line-by-line description for those of you who wish to analyze
the program.
10 This line stores values in variables for easy access.
20 (ESC) "1" sets the line spacing to 7/72 inch. The (ESC) "0" se-
quence sets a horizontal tab stop at column 26.
30 The (ESC)":" string copies the entire ROM character set into
RAM. See Chapter 17.
40 Designates RAM as the source for the active character set.
50 Prepares the printer to redefine characters 0 through
@.
60 Sets a counter for the 17 letters being defined and prints the "at-
tribute byte" of each new character.
70 Reads the data that defines the letters (17 sets of 11).
80 Turns on Unidirectional Mode.
90 Prints the top of the ticket and sets the line feed to 6/72 inch.
100 Prints the newly defined symbol" (" (ticket border), tabs to the
next stop, prints the other border
(»),
and sets the line spacing
back to 7/72 inch.
110 After printing the outside border, this line prints the top of the
inside border (which was defined as the zero character).
120 Gives another line of borders.
130 This line prints more borders, then sets the Master Select Mode
type style 24 or X. (That's Emphasized, Double-Strike, and Pica
combined in one code!) The ESCape "4" turns Italic ON and
(ESC) "-1" turns ON Underline Mode.
