The Assembly Language Processor (ALP) is a macro assembler from IBM that offers a native mode and a MASM 5.1 compatible mode, and indeed intended to replace the Microsoft Assembler product for use on OS/2 systems especially for driver development. ALP was available in versions for OS/2 and AIX, versions with dates later than 1995 also support a subset of the MASM 6.x language.

Features

ALP generates standard OMF files that can be linked to produce DOS or OS/2 executables. Symbolic debugging information is compatible with IBM's source code debuggers.

Add-ons

• ALP_MXG - By default the native mode on ALP is 32 bits only while the otherwise less capable MASM 5.1 emulation mode allows mixed 16/32 bit code. This patch allows you to use mixed 16/32 bit code in native ALP mode.
• masm2alp - Utility that converts MASM projects to ALP projects.
