Header: Apple Writer IIe under DOS 3.3: Printer codes from all Apples

 Many printers have special features that the computer signals by sending
 command codes. To send codes to a printer from  Apple Writer IIe under DOS
 3.3,
 you must insert the codes into the Apple Writer file you want printed. The
 manual of the printer may list the codes by several names: decimal,
 hexadecimal, teletype abbreviations (SOH, ETX, DC1, DC3, etc.), standard keys,
 and combinations of the above.

 Using the chart "ASCII characters, values, and keystrokes", you have to
 translate from the name of the code in the printer manual into the name of the
 corresponding keystroke or keystrokes on the keyboard of the Apple IIe,
 Enhanced Apple IIe, or Apple IIc.

 Some keystrokes put so-called control characters into the Apple Writer file.
 These control characters are not part of the conventional English character
 set; while screen shows them, the printer intercepts and does not print them,
 instead recognizing them as signals to turn special functions on and off or to
 change printer settings.

 NOTE: In the descriptions of the keystrokes, the characters greater than and
      less than, < and >, are used to contain one keystroke, which can mean
      that:
      1. You must simultaneously hold down the control key, the shift key, or
         both as you press the other key, or
      2. You must press a special key, such as ESC or RETURN.

 With these considerations in mind, here is a list of codes and methods for
 inserting them in an Apple Writer file.

 Null (ASCII value 0):

 The following patch is for Apple Writer IIe under DOS 3.3. The patch allows
 you
 to enter NULs (CTRL-@) when in CTRL-V mode.  The only side-effect is that the
 DELETE key doesn't work for correcting a filename entered from the keyboard
 for
 the DOS COMMANDS or ADDITIONAL FUNCTIONS menu; instead, just use the left
 arrow
 key.

 --Boot the DOS 3.3 System Master diskette.

 --Remove the System Master diskette, insert the Apple Writer IIe under DOS 3.3
  diskette and type the following commands.

 BLOAD OBJ.APWRTIIE
 CALL -151
 1CE1:EA EA EA EA
 3EBA:EA EA EA EA
 3D0G
 UNLOCK OBJ.APWRTIIE
 BSAVE OBJ.APWRTIIE,A$1900,L$2F58
 LOCK OBJ.APWRTIIE
 BLOAD OBJ.APWRTIIF
 CALL -151
 1D81:EA EA EA EA
 4033:EA EA EA EA
 3D0G
 UNLOCK OBJ.APWRTIIF
 BSAVE OBJ.APWRTIIF,A$1900,L$30D1
 LOCK OBJ.APWRTIIF

 If you don't want to do this to your Apple Writer IIe diskette, refer below to
 the Applesoft BASIC solution.

 Control-A through Control-Z (ASCII decimal values 01 through 26):

    Example: Control-Z (ASCII decimal value 26): <CTRL-V><CTRL-Z><CTRL-V>

    Exception: Control-V (ASCII decimal value 22) can't be entered.
               See "Missing Characters" below.
 Escape (ASCII value 27): <CTRL-V><ESC><CTRL-V>

 Other Control characters: These can be entered in the manner of Control-A
 through Control-Z.

 Missing Characters:

 You can't directly enter a Control-V in Apple Writer. To use these and other
 characters in Apple Writer, it is necessary to use an Apple Writer glossary
 file.

 Apple Writer doesn't send a Null character.

 Applesoft BASIC can be used to send a Null character to your printer.

 1. Create your Apple Writer document as usual, but substitute a unique
 character in each place that you want a Null character.

 2. Type <CTRL-P> to display the Print/Programs Command menu.

 3. Type PD8, Apple Writer's code for Print to Disk on an Apple II.

 4. Type NP to begin printing.

 5. To the Apple Writer prompt for a file name, do not enter the same name with
 which the file is already saved. Enter a unique name, and note it down.

 6. After the printing to disk is finished, exit Apple Writer and boot up a
 ProDOS diskette.

 7. Run the following program:

 100 HOME
 110 PRINT TAB(10);APPLE WRITER TO PRINTER"
 120 VTAB 5
 130 INPUT "NAME OF APPLE WRITER FILE PRINTED TO DISK: ";F$
 140 IF F$="" THEN 900
 145 VTAB 12
 146 INPUT "CHARACTER TO REPLACE: ";X$
 147 IF X$="" THEN 145
 150 VTAB 10
 160 INPUT "PRINTER SLOT #: ";S$
 170 IF S$="" THEN 900
 180 S=VAL$(S$); IF S < 1 OR S > 7 OR INT(S) <> S THEN 150
 190 D$=CHR$(4)
 200 ONERR GOTO 800
 210 PRINT D$;"UNLOCK";F$
 220 POKE 216,0
 230 VTAB 12: PRINT SPC(75)
 240 PRINT
 250 PRINT D$;"PR#";S
 260 PRINT CHR$(9);"132N"
 270 PRINT D$;"OPEN";F$280 ONERR GOTO 400
 290 PRINT D$;"READ";F$ 300 A$=""
 310 GET C$
 315 IF C$=CHR$(12) THEN 310
 320 IF C$=CHR$(13) THEN 350
 330 IF C$=X$ THEN C$=CHR$(0)
 340 A$=A$+C$:GOTO 310
 350 PRINT A$
 390 GOTO 300
 400 POKE 216,0
 410 PRINT D$;"CLOSE"
 420 PRINT D$;"PR#0"
 430 VTAB 15
 440 PRINT TAB(5);"FILE ";F$;" HAS BEEN PRINTED."
 450 GOTO 900
 800 POKE 216,0
 810 VTAB 12
 820 PRINT CHR$(7);"I CAN'T FIND THE FILE ";F$;"."
 830 INPUT "";Z$
 840 GOTO 100
 900 END
