3.1 General Format of AUTOBK.INP

Commands to autobk are read from the file autobk.inp. These input commands name the data file to use for the data and set all user options and controls. autobk uses keywords to describe and assign values to all program parameters. The use of keywords allows the input file to be read easily and the values of the program parameters to be modified easily. The keywords have fairly transparent meanings, and are assigned values with keyword ``sentences'' with syntax:

keyword value.

The keyword must be one of the valid keywords listed below. The is an equal sign or white space (a blank or TAB) surrounded by any number of white spaces. The value is provided by the user and will be interpreted as a number, a logical flag, or a character string, depending on the nature of the keyword -- the list below will indicate what kind of value each keyword takes. Logical flags all have values true or false (t and f will work, too). If a keyword's value is a number or logical flag (but not a character string), the assigning keyword sentence can be put on the same line as other numerical and logical keyword sentences. Keywords that take character strings as their value must occur on their own line. autobk does not distinguish keywords by case. But to accommodate many operating systems, it does distinguish the names of external files by case. Keyword sentences are allowed to occur in any order in the file. Internal comments can be written anywhere in autobk.inp.
