Table Of Contents
determine which attributes, hence which blocks, are included in the attribute
extraction file. If a block contains some, but not all, of the specified attributes,
the values for the absent ones are filled with blanks or zeros, depending on
whether the field is a character field or a numeric field.
Comments should not be included in an attribute template file.
The illustration and table show an example of the type of information you're
likely to extract, including block name, manufacturer, model number, and
cost.

You can create any number of template files, depending on how you'll use
the data. Each line of a template file specifies one field to be written in the
attribute extraction file.
Follow these additional guidelines:
Be sure to place a space between the attribute tag and the character or
numeric data. Use Spacebar, not Tab, to enter the space.
Press Enter at the end of each line, including the last line.
Each attribute extraction template file must include at least one attribute
tag field, but the same field can appear only once in the file.
The following is a sample template file.
BL:NAME C008000 (Block name, 8 characters)
