gtpp2m06 | Programming Standards |
This book presents programming standards used by TPF Development. The standards manual contains information, methods, and examples for implementing user programs compatible with TPF.
This manual contains both statements of standards and examples of standards. The materials used to illustrate standards may not be entirely up-to-date with the current product (for example, the text of an operator message may be changed); they only serve to indicate the points being made. Strict accuracy with a changing product need not be achieved when the intent is solely the purpose of illustration.
In this book, abbreviations are often used instead of spelled-out terms. Every term is spelled out at first mention followed by the all-caps abbreviation enclosed in parentheses; for example, Systems Network Architecture (SNA). Abbreviations are defined again at various intervals throughout the book. In addition, the majority of abbreviations and their definitions are listed in the master glossary in the TPF Library Guide.
This book is intended for application and system programmers, and for programming managers.
The TPF library uses the following conventions:

Scale | Used to indicate the column location of input. The scale begins at
column position 1. The plus sign (+) represents increments of 5
and the numerals represent increments of 10 on the scale. The first
plus sign (+) represents column position 5; numeral 1 shows column
position 10; numeral 2 shows column position 20 and so on. The
following example shows the required text and column position for the image
clear card.
