Turbo Assembler (sometimes shortened to the name of the executable, TASM) is an assembler for software development published by Borland in 1989. It runs on and produces code for 16- or 32-bit x86 MS-DOS and compatibles for Microsoft Windows. It can be used with Borland's other language products: Turbo Pascal, Turbo Basic, Turbo C, and Turbo C++.
x86 assembly language has two primary syntax branches: Intel syntax and AT&T syntax. [6] Intel syntax is dominant in the DOS and Windows environments, while AT&T syntax is dominant in Unix-like systems, as Unix was originally developed at AT&T Bell Labs. [7] Below is a summary of the main differences between Intel syntax and AT&T syntax:
In the x86 assembly language, the TEST instruction performs a bitwise AND on two operands. The flags SF, ZF, PF are modified while the result of the AND is discarded. The OF and CF flags are set to 0, while AF flag is undefined. There are 9 different opcodes for the TEST instruction depending on the type and size of the operands. It can compare ...
In computer programming, assembly language (alternatively assembler language [1] or symbolic machine code), [2] [3] [4] often referred to simply as assembly and commonly abbreviated as ASM or asm, is any low-level programming language with a very strong correspondence between the instructions in the language and the architecture's machine code instructions. [5]
Turbo Debugger (TD) is a machine-level debugger for DOS executables, intended mainly for debugging Borland Turbo Pascal, and later Turbo C programs, sold by Borland.It is a full-screen debugger displaying both Turbo Pascal or Turbo C source and corresponding assembly-language instructions, with powerful capabilities for setting breakpoints, watching the execution of instructions, monitoring ...
Support for the various x86 memory models was provided by inline assembly, compiler options, and language extensions such as the "absolute" keyword. The Turbo Assembler, TASM, a standard x86 assembler independent of TP, and source-compatible with the widely used Microsoft Macro Assembler MASM, was supplied with the enhanced "Borland Pascal ...
High-Level Assembly (HLA) is a language developed by Randall Hyde that allows the use of higher-level language constructs to aid both beginners and advanced assembly developers. It supports advanced data types and object-oriented programming .
Modifies stack for entry to procedure for high level language. Takes two operands: the amount of storage to be allocated on the stack and the nesting level of the procedure. INSB/INSW: 6C Input from port to string. May be used with a REP prefix to repeat the instruction CX times. equivalent to:
