Specification format for Facets
Each specification is of the form:
Specification = Value
Specifications have particular meanings to Facets,
e.g., Title= specifies the heading line for the report tables.
Value is what you assign to the specification, e.g., Knox Cube Test
Thus, to title your Facets report Knox Cube Test, specify
Title = Knox Cube Test
Refer to these if you can't get your specifications to work:
a. Each specification goes on a separate line in the specification file.
b. Only the first one or two letters of each specification line matter. Title= or Titel= or T= all mean the same thing. Just enough letters are needed to identify the specification uniquely.
c. Upper or lower case letters are treated the same in defining specifications. Title= or title= mean the same thing.
d. Whatever follows a semi-colon ";" is ignored as a comment.
e. Blank lines are ignored, also ASCII 160 (hex A0) codes.
f. Leading and trailing blanks around any value are ignored. "3,Mary,2.3,1" is the same as " 3 , Mary, 2.3, 1"
g. Equal signs, "=", and commas, "," are separators which can be used interchangeably.
h. Each line must terminate with carriage return+line feed, (the standard option for printed or DOS text files). If using a word processor to prepare your specifications or data, be sure to output the files in DOS or ASCII format.
i. Facets= instruction should precede any other instructions that contain facet numbers.
= , tabs
ignored, but can act as separators in data lines
comments - ignored
comments - ignored but listed in output file.
Values in control specifications can be separated by commas "," or equal signs "=" or tabs (ASCII 9 codes), so that these control instructions have the same meaning:
positive = 1,2,3,4 ; blanks around values are ignored.
positive = 1=2=3=4
positive , 1 , 2 , 3 , 4
positive = 1 2 3 4 ; these numbers are separated by Tab codes
