What is ASMLIB?

ASMLIB is a library of assembly-language subroutines, linkable with
your .OBJ code. ASMLIB provides many tools to the assembly-language
programmer which eliminate much of the tedious and repetetive coding
that assembly-language programming is infamous for.

DISTRIBUTION AND REGISTRATION

ASMLIB is user-supported software, NOT public domain software.
Possession of the ASMLIB files entitles you to evaluate this product.
If, after evaluation, you choose to use ASMLIB subroutines in your
programs, you are expected to register with the library's author.
By registering, you will be entitled to use the latest version of ASMLIB,
you will be entitled to low-cost upgrades, you will have confidence that
the version of ASMLIB you are using has not been altered by others, and
you will be supporting my programming efforts.

Two levels of registration are available: For $25, you will recieve the
most recent version of ASMLIB (tiny, small, medium and huge models); for
$50 you will receive full source code to the ASMLIB subroutines along with
the assembled libraries. If you first register at the $25 level, you may
register for ASMLIB source code at any time for $25. Upgrades for either
level of registration are $10.

Register by sending the registration fee to:

Douglas Herr
P. O. Box 207
Sacramento, CA 95812
U.S.A.

Telephone (916) 721-8762
CompuServe 71247,3542

Please specify either 5 1/4 or 3 1/2 inch disks. Bug reports (if any)
should be sent to the same address. If you wish to contact me by
telephone, please call after 8:00 PM Pacific time so I can get my kids
in bed.

Registration is a LICENSE fee, not a purchase of ASMLIB. Registered users
may use ASMLIB or modified subroutines based on ASMLIB source code in their
own programs. Registered users may distribute programs using ASMLIB
subroutines without royalty payments.

ASMLIB object files, ASMLIB source code (unmodified or modified) and the
ASMLIB library and documentation remain the property of Douglas Herr.

LIMITED LIABILITY

Since I am unable to supervise all uses of ASMLIB, I cannot be held
responsible for any damages, either direct or incidental, resulting
from the use or abuse of ASMLIB. I have used ASMLIB subroutines on
a wide variety of equipment and have found the library to be highly
compatible with common PC equipment, but you must use this library at
your own risk. Try it before you buy it.


COMPATIBILITY

ASMLIB subroutines are intended for IBM PC, XT, AT, PS/2, and compatible
equipment in real mode with PC-DOS or MS-DOS operating systems. I cannot
provide support for use of ASMLIB on other equipment or with other operating
systems.


ABBREVIATIONS for video boards

CGA IBM-standard Color Graphics Adapter (ugh!)
MCGA IBM-standard Multi-color Graphics Array
EGA IBM-standard Enhanced Graphics Adapter
VGA IBM-standard Video Graphics Array
SVGA VGA equipment with additional capabilities
ATT ATT 6300 and compatible Olivetti
HGC Hercules Graphics Card and compatibles
HGC+ Hercules Graphics Card Plus
InC Hercules InColor Card

OTHER ABBREVIATIONS

CF = Carry Flag
ZF = Zero Flag
SF = Sign Flag


ASSUMPTIONS

Unless otherwise stated, ASMLIB subroutines assume that:

1) All strings are terminated with a NUL character.

2) Subroutines with names including '$' trash registers, and are
intended primarily for ASMLIB's internal use. All '$' subroutines
require a near call. Documentation for '$' subroutines is in
SOURCE.DOC, provided to registered ASMLIB programmers.

3) ASMLIB subroutines without '$' in the name require a far call, and
are compatible with object files assembled with the

.model medium

directive. Subroutines in ASMSMALL.LIB, provided upon registration,
require a near call, and are compatible with object code assembled with
the

.model small

directive. Subroutines in ASMTINY.LIB, provided to registered
programmers, also require near calls and are intended for development
of .COM format programs. ASMTINY is compatile with object code assembled
with the TASM

.model tiny

directive. MASM users may use the TINY.INC include file to achieve the
same results. Subroutines in ASMHUGE.LIB, also provided upon
registration, includes support for data blocks > 64k. Support
for huge data is indicated in the description of each subroutine.

Aside from the MODEL.INC include file and parameters as required for
HUGE model programming, ASMLIB source code does not need any alteration
when changing memory models. All ASMLIB source code is compatible with
MASM 5.0, MASM 5.1 and TASM 2.01.

4) ASMLIB data types are:

chr 1 byte
str character string, normally terminated with ASCII 0 (NUL)
I2 2-byte signed integer
U2 2-byte unsigned integer
I4 4-byte signed integer
U4 4-byte unsigned integer
F4 4-byte floating point value, IEEE format
F8 8-byte floating point value, IEEE format

5) ASMLIB GRAPHICS subroutines assume DS:@DATA

HOW DO I USE ALL THIS NEAT STUFF?

Any program that calls an ASMLIB subroutine must declare the subroutine as
an external procedure, like this:

extrn gedit:proc ; tell assembler to assume that GEDIT is an external
; procedure to be linked later


I also find it handy to make LINK search through ASMLIB for object code,
rather than specifying ASMLIB on the command line. Do this with the
command

includelib asmlib.lib ; automatic search through ASMLIB for externals

in your calling program. See STARTUP.ASM. (Note: this may not work with
TASM 2.01 & TLINK. You will need to specify ASMLIB on the command line.)


CALLING ASMLIB FROM C PROGRAMS

It's easy to call ASMLIB subroutines from C if you follow these simple
rules (Turbo C examples):

1) Tell your C program that the ASMLIB subroutine is a PASCAL function
This makes the C compiler convert the subroutine name to upper case
and supresses the _leading _underscore in the subroutine name.

Example:
extern void pascal tprint();


2) In case of naming conflicts (such as strlen), declare the ASMLIB
subroutine in upper case and use upper case in the C code.

Example:
extern void pascal STRLEN();
.
.
.
_BX = msg; /* pointer to ASCIIZ string */
STRLEN(); /* ASMLIB subroutine */
string_length = _CX


3) Load the 80x86 registers before calling the ASMLIB subroutine.

Example:
_DX = 0; /* upper left corner of screen */
_AH = 15; /* bright white */
_SI = msg; /* pointer to ASCIIZ string */
tprint();


4) ASMLIB subroutines using the 8087 will use Turbo C's
emulation library if re-assembled with the /E option.


5) values in registers returned by ASMLIB subroutines should be used
or saved immediately; C code executed after calling an ASMLIB
subroutine may change any of the registers


6) When compiling from within the Turbo C editor, include ASMLIB.LIB
in your .PRJ file (ASMSMALL.LIB for small model, ASMHUGE.LIB for
huge model).


DOCUMENTATION

There's alot of stuff in ASMLIB, so I've tried to keep the documentation
succinct. Here's a general guide to ASMLIB's documentation:



SUBROUTINE: a brief description
Source: the source code file (and other subroutines used)

Call with: this tells you what data the subroutine expects
additional information may be found here

Returns: tells you what registers and/or flags contain useful info
Additional lines may include more specific information about
the register values returned.
Uses: registers and flags which may be changed
Supports: particular equipment or operating modes; this will not apply to
all subroutines.
Example: an example of how parameters are passed to the subroutine
and a typical use of the subroutine.
