Introduction to TFORM
3–150 11387 Tandem Computers Incorporated
The algorithm TFORM uses to add spaces in sentences places one space
between words within a sentence and two spaces after sentences
(determining the end of a sentence with the conditions listed above).
Two unusual conditions cause TFORM to add only one space instead of
two between sentences
a. The first case is a sentence ending with a single character; for
example, “We now move on to Category 3.” TFORM doesn’t
recognize single characters as words, so to TFORM, the sentence
has not ended.
b. The second case is a sentence that does not begin with a letter; for
example, “1849 was a year of gold fever.” Here, TFORM does not
see a new sentence starting.
To correct these anomalies, you can use the STYLE SENTENCES
VERBATIM command or add a required blank character (\#, a
metacharacter described in Section 4) after the punctuation to ensure an
extra space.
If you are not using a 5530 printer, TFORM rounds a fractional num
value to the nearest number of whole lines.
