The PDL/81 Processor
The PDL/81 processor completely removes the burden of presenting PDL designs in documents which have a consistent form and high standard.
PDL/81 can be used at any time during a project to print a
fully-legible, cross-referenced design document.
The layout encourages fast understanding by the reader, while the
deliberately economical use of visual enhancements prevents the impact
of a page detracting from its content.
It doesn't matter if a design is incomplete: PDL/81 will always
produce a complete design document in which the unfinished parts will
Even an early design sketch can be documented with PDL/81.
At its simplest level, PDL/81 automatically does such things as:
Each of these functions is illustrated in
- printing each flow segment on a separate
- highlighting keywords;
- indenting statements to correspond to nesting levels;
- detecting and cross-referencing calls from one
flow segment to another; and
- detecting and cross-referencing the use of data items.
Beyond these functions, the power and flexibility of PDL/81 is
considerable virtually every aspect of the design document
can be changed.
In practice, it is common for a design team to create its own
house-style for design documents by using the
Format Design Language component of PDL/81.
can be added, perhaps to match the implementation language;
- visual enhancements can be changed;
- specialized indexes can be created;
- a great deal of useful information about a design can be accumulated
and reported by PDL/81 by using facilities such as
Complexity Analysis, Consistency Checking, and
Automatic Requirements Tracking.
A full list of the capabilities of PDL/81 is presented
in the next section.
In addition to software designs, PDL/81 is a complete text
processor for conventional documents such as manuals, reports,
letters, and memos.
In fact, all the documents associated with software development can be
produced using the same tool.
