2title DOS Print Utility
3
4;MS-DOS PSPRINT/PRINT program for background printing of text files
5; to the list device.
6;
7; IBM SERVER VERSION
8;
9; INT 28H is a software interrupt generated by the DOS
10; in its I/O wait loops. This spooler can be assembled for
11; operation using only this interrupt which is portable from
12; system to system. It may also be assembled to use a hardware
13; timer interrupt in addition to the software INT 28H. The
14; purpose of using hardware interrupts is to allow printing to
15; continue during programs which do not enter the system and
16; therefore causes the INT 28H to go away. A timer interrupt is
17; chosen in preference to a "printer buffer empty" interrupt
18; because PRINT in the timer form is generic. It can be given
19; the name of any currently installed character device as the
20; "printer", this makes it portable to devices which are
21; installed by the user even in the hardware case. It could be
22; Revised to use a buffer empty interrupt (no code is given for
23; this case), if this is done the PROMPT and BADMES messages and
24; their associated code should be removed as PRINT will then be
25; device specific.

47; Aaron's rambling:
48;
49; BEWARE ALL YEE WHO ENTER HERE.
50; PRINT is an amazingly complex program. MS-DOS versions below 3.00 are
51; NOT re-entrant, this means that this utility is basically not a
52; possibility. It gets by on the fact that it is written by the same
53; person who wrote the OS. Since you are not that person, you must be very
54; careful about making any modification to this utility. There are a
55; number of things which may seem to be unnecessary on first examination.
56; BEWARE, almost every line of code is there for a very good reason. The
57; order of things is very carefully chosen. PRINT is full of potential
58; windows, make sure that you do not open one by careless modification. Do
59; not look for a lot of help from the comments, a complete explanation
60; would probably fill a book. A succesful modifier will have an in-depth
61; knowledge of the internal function of MS-DOS, and of the PRINT utility
62; itself through in depth study of the comments AND the code.

3359; the message service code is NOT used to display RESIDENT messages.

3363; OUTPUT: Resident messages loaded into the resident message buffer
3364; and Message Sevices code initalized
3365;
3366; NOTE: Messages ERRO through ERR12, ERRMEST through AllCan, FATMES
3367; BADDDRVM, GOODMES and BADMES are used in place - whereever
3368; the Message retriever points to them. BADDRVM is moved directly behind
3369; FATMES.
3370;
