The Assembly Language Processor (ALP) is an assembler that runs under OS/2 Warp. ALP is a functional replacement for the Microsoft Macro Assembler (MASM) and accepts:
ALP generates standard Object Module Format (OMF) files that can be linked to produce DOS or OS/2 executables. It can also generate symbolic debugging information compatible with the IBM family of source code debuggers. A MASM 5.10-compatible command line utility (MASM2ALP) is also provided to enable use of ALP with little or no change to existing build environments.
ALP also offers a rich set of command line options, as well as a comprehensive listing output cabability that is highly configurable, allowing a visual perspective not possible with other assemblers.
