View source for IBM Assembly Language Processor

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.

* The Hobbes [http://hobbes.nmsu.edu/h-browse.php?dir=/pub/os2/dev/asm DEV/ASM directory] contains most of the ALP tools and patches.

;Add-ons
* [http://hobbes.nmsu.edu/h-search.php?key=ALP_MXG&pushbutton=Search 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.
