was introduced in 1992 replacing IBM's H assembler.
High Level Assembler (
), announced in 1992 as a licensed program "becomes the default translator for System/370 (TM) and System/390 (TM) operating environments." The assembler supports the MVS, VSE, and VM operating systems and successors. As of Release 6 it now is able to run under Linux on zSeries and generate ELF or COFF object files. It features a long list of mostly usability enhancements, and incorporates the SLAC (Stanford Linear Accelerator) modifications to Assembler H. Among features added were an indication of CSECT/DSECT for location counter, a list of "using" registers currently active, an indication of whether a variable is read or written in the cross-reference, and allowing mixed-case symbol names. The "RSECT" directive (Read-only Control Section) allows the assembler to check reentrancy on a per-section basis. RSECT was previously "undocumented and inconsistently implemented in Assembler H."
is the current assembler for IBM mainframe systems as of 2012.
High Level Assembler or
is IBM's current assembler product for its z/OS, z/VSE, z/VM and z/TPF operating systems on z/Architecture mainframe computers. There is also a version that runs on Linux, primarily intended for systems running on a z/Architecture system (this environment is sometimes referred to as z/Linux).
Despite the name
on its own does not have many of the features normally associated with a high-level assembler, but does offer a number of improvements over Assembler H and Assembler(XF), such as labeled and dependent USINGs, more complete cross-reference information, and additional macro language capabilities such as the ability to write user-defined functions.
Much development work was done on S/360 or S/370 using a variation of the
program geared to the MSP/7 macro language. To provide more flexibility in programming the System/7, a group in the IBM San Jose Research Laboratory in San Jose, California developed the LABS/7 operating environment, which with its language Event Driven Language (EDL), was ported to the Series/1 environment as the very successful Event Driven Executive (EDX).
Assemblers on other System/360 operating systems through System/370, System/390, and System z, as well as the UNIVAC Series 90 mainframes made by Sperry Corporation, and the BS2000 Mainframes currently made by Fujitsu, inherited and extended its syntax. The latest derived language is known as the IBM High-Level Assembler (
). Programmers utilizing this family of assemblers also refer to them as ALC, (for Assembly Language Coding), or simply "assembler".
The earliest high-level assembler was probably Burroughs ESPOL in about 1960, which provided an ALGOL-like syntax around explicitly-specified B5000 machine instructions. This was followed by Niklaus Wirth's PL360 in 1968, this replicated the Burroughs facilities, with which he was familiar, on an IBM System/360. More recent high-level assemblers are Borland's TASM, NASM, Microsoft's MASM, IBM's
(for z/Architecture systems), Alessandro Ghignola's Linoleum and Ziron.
