ASMLIB 3.8 Programmer's Toolkit tools for 16-bit assembly-language programming Copyright (C) 1991 - 1994 Douglas Herr - All rights reserved 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 ASMLIB (tiny, small, medium and huge models, for all PCs and for 286 or better PCs); 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. ASMLIB source code, modified or unmodified, may not be re-distributed. The ASMLIB3 shareware package includes these files: ASMLIB.LIB the ASMLIB medium model library ASMLIB.DOC this introductory file DATA.DOC documentation for string and integer data manipulation DISK.DOC documentation for disk & file subroutines EMSXMS.DOC documentation for EMS and XMS subroutines FLOAT.DOC documentation for floating-point subroutines GRAPHICS.DOC documentation for ASMLIB graphics INPUT.DOC documentation for keyboard input subroutines MODE.DOC ASMLIB screen mode subroutines MULTIWIN.DOC documentation for text-mode multi-window subroutines SOLVE.DOC documentation for ASMLIB mathematical solutions SYSTEM.DOC documentation for subroutines which determine PC status TEXT.DOC documentation for text-mode video subroutines STARTUP.ASM sample startup code ASM.INC medium model INCLUDE file for STARTUP.ASM E16.COM handy text editor developed with ASMTINY.LIB E16.DOC E16.COM documentation These files may be copied and distributed freely provided that all the above files are distributed together in unmodified or archived form and provided that distribution charges are less than $10. LIMITED LIABILITY Since I am unable to supervise all uses of ASMLIB, I cannot be held responsible for any damages, either direct or incidental, resulting from the use or abuse of ASMLIB. I have used ASMLIB subroutines on a wide variety of equipment and have found the library to be highly compatible with common PC equipment, but you must use this library at your own risk. Try it before you buy it. COMPATIBILITY ASMLIB subroutines are intended for IBM PC, XT, AT, PS/2, and compatible equipment in real mode with PC-DOS or MS-DOS operating systems. I cannot provide support for use of ASMLIB on other equipment or with other operating systems. ABBREVIATIONS for video boards MDA IBM-standard Monochrome Display Adapter CGA IBM-standard Color Graphics Adapter (ugh!) MCGA IBM-standard Multi-color Graphics Array EGA IBM-standard Enhanced Graphics Adapter VGA IBM-standard Video Graphics Array SVGA VGA equipment with additional capabilities ATT ATT 6300 and compatible Olivetti HGC Hercules Graphics Card and compatibles HGC+ Hercules Graphics Card Plus InC Hercules InColor Card OTHER ABBREVIATIONS CF = Carry Flag DF = Direction flag SF = Sign Flag ZF = Zero Flag ASSUMPTIONS Unless otherwise stated, ASMLIB subroutines assume that: 1) All strings are terminated with a NUL character. 2) Subroutines with names including '$' 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 and 286LIB 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 and 286SMALL.LIB, provided upon registration, require a near call, and are compatible with object code assembled with the .model small directive. Subroutines in ASMTINY.LIB and 286TINY.LIB, provided to registered programmers, also require near calls and are intended for development of .COM format programs. ASMTINY is compatible 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 and 286HUGE.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. (This may not work with some versions of TLINK. You will need to specify ASMLIB on the command line or in TLINK's response file.) 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.
