  Design considerations for an assembler
As the pressure actuated ratchets are inside the assembler and the source of the pressure changes is outside, we must insure that pressure changes are transmitted with reasonable accuracy from the outside to the inside.
Because a new assembler is manufactured inside an existing assembler, reducing the volume occupied by the pressure equilibration subsystem in its compact state (i.e., the state in which it is manufactured) is advantageous.
While this process is clearly wasteful (retaining the parent assembler in a functional state would be desirable), it simplifies the design of the extrusion process as the hollow shell is called upon to perform only a single task, rather than also acting as the wall of the new assemblers.

 Assembler coding - hints, tips, guidelines, FAQ etc   (Site not responding. Last check: 2007-11-05)
However there is a surprising amount of assembler code still in use, and while much has disappeared as the result of Y2K work, any code that has survived the millennium will be around for quite a while.
Moreover the on/off coming of the Euro in the UK may mean that much UK assembler will have to be re-visited soon and assembler programming may have a small period of demand.
Many newcomers to assembler (and old hands who are being lazy!) write code that has hard-coded values etc. This might even be OK for a 5 line program, but creates difficulties in the 50 line program and will make system maintenance a nightmare for the 500 or bigger line program.

 HLASM - Why assembler?
On the one hand are the arguments against the use of assembler in large part prejudicial, on the other hand are the arguments for the use of assembler relatively unknown.
In assembler storage can be allocated and de-allocated dynamically, enabling you to grow or shrink your in-storage objects to the required size.
Assembler is indeed a little less readable to the layman than e.g.

 [No title]   (Site not responding. Last check: 2007-11-05)
The assembler adjusts the size of the segments taking as a base the number of bytes each assembled instruction needs, since it would be a waste of memory to use the whole segments.
What the assembler does to generate the OBJ code is to read each one of the tokens and look for it on an internal "equivalence" chart known as the reserved words chart, which is where all the mnemonic meanings we use as instructions are found.
Sometimes the assembler comes on a token which is not defined on the program, therefore what it does in these cased is to pass a second time by the source program to verify all references to that symbol and place it on the symbols chart.

 Softpanorama: Assembler is not for Dummies
I am convinced that assembler is a fundamental part of a programmer education and that a person that learned assembler has a better chance to became a good programmer that a person that spend the same amount of time on learning some fancy languages and/or programming methodologies like object-oriented programming ;-).
Assembler probably should not be the first language, the first language should be something simple like old good Basic or may be JavaScript (the ability to generate HTML is pretty exiting for an introductory programming course), but it probably should be the second language.
The latter is especially important for assembler programmers as Donald Knuth is one of few computer scientists who was able to see thru "object-oriented programming" smog and defend the value of the assembler language both for computer science education and for real and complex programming projects.

 Webster: Roll Your Own at Home: Writing Your Own Assembler
Writing an assembler is a good medium-sized project that many beginning to intermediate programmers can handle, allowing them to sharpen their programming skills on a practical project.
Creating a "hobby-quality" assembler isn't a difficult task, but creating a "commercial-quality" assembler with a professional feature set is a large project, often requiring skills that beginning to intermediate programmers don't possess.
Assemblers designed around the ADK will be very fast (most of the time-consuming algorithms you'll find in an assembler are already efficiently implemented in the ADK).

 Art of Assembly Language Programming and HLA by Randall Hyde
With so many different assemblers to choose from, one problem crops up: the need to translate from one assembler to another (i.e., you've decided to use one assembler and you've written all this source code with that assembler, now someone wants to assemble your source code with a different assembler).
The bottom line is that HLA is not a popular assembler with yesterday's generation of assembly language programmers, but it is poised to become a very popular assembler with the next generation of assembly language programmers coming down the pike.
Indeed, many assemblers' authors (like A(3)86) made a point of promoting the fact that their assemblers had fewer features than MASM and, therefore, were easier to learn and use.

There are several excellent guides to assembler programming and windows programming on the internet, but if these are based on source code for other assemblers or for "C", they can be confusing for the beginner who wants to use the "Go" tools.

 A Manual for the Plan 9 assembler
All pre-defined symbols in the assembler are upper-case.
Assembler instructions should be laid out as if there were no load, branch, or floating point compare delay slots; the loader will rearrange—schedule—the instructions to guarantee correctness and improve performance.
The assembler often accepts the handbook’s name to ease conversion of existing code (but remember that the operand order is uniformly source then destination).

 Core J2EE Patterns - Transfer Object Assembler
Therefore, it is recommended that the assembler be a stateless session bean to leverage the benefits of stateless over stateful session beans.
The Transfer Object Assembler hides the complexity of the construction of model data from the clients and establishes a loose coupling between clients and the model.
However, the Transfer Object Assembler is more applicable when the composite Transfer Object constructed is derived from a number of components (session beans, entity beans, DAOs, and so forth), whereas the Composite Entity pattern constructs the Transfer Object from its own data (that is, a single entity bean).

The other key to practical molecular manufacturing is the ability to fabricate massive quantities of molecularly precise structures, or to assemble larger objects from vast numbers of molecularly precise smaller objects –; that is, massively parallel assembly.
The end result of this development process will be a basic molecular assembler that employs machine-phase nanotechnology (e.g., nanoscale gears, struts, springs, motors, casings) to fabricate molecularly precise diamondoid structures, following a set of instructions to build a desired specific design.
This will be followed by discussions and examples of specific nanomechanical components and compound machines including bearings, fasteners, gears, linkages, drive mechanisms, motors and pumps, mechanical energy controllers, sensors, and programmable materials.

 Design of a SPARC assembler
The assembler determines the size of the assembled machine code and initialized data during its first pass over the input file.
The assembler ignores debugging symbols ("stabs") during the first pass, since debugging symbols can refer to other symbols, but nothing refers to the debugging symbols.
The assembler generates simple parse trees that amount to little more than a direct transliteration of a line of assembly into a C struct.

 What is assembler? - a definition from Whatis.com - see also: assembly language, assembler language
This sequence of assembler instructions, known as the source code or source program, is then specified to the assembler program when that program is started.
The assembler program takes each program statement in the source program and generates a corresponding bit stream or pattern (a series of 0's and 1's of a given length).
The output of the assembler program is called the object code or object program relative to the input source program.
