a pointing device that is operated by rotating a ball.
trackpad
(trak' pad') n.
a pointing device that is operated by moving a fingertip across a flat surface.
trailing
(trAl' ing) adj.
at the end of a text value.
trailing space
n.
a space or one of several spaces at the end of a text value. SAS disregards trailing spaces when it makes character comparisons.

truncate
(trung kAt') n.
1. to shorten an object by removing part of it.
2. to remove characters from the end of a character string. The SAS supervisor does this automatically when it assigns a character expression to a shorter character variable.
3. to convert a real number to an integer by rounding toward 0, removing the fractional part of the number.
4. to reduce the precision of a floating-point number by removing its least significant bytes or changing them to zero.
truth table
n.
a diagram that shows the results of a logical expression for each combination of logical values in the expression.
try
(trI') v.t.&i.
1. to take an action for the purpose of determining its results.
n.
2. an action for which the results are unknown or for which success is uncertain.
3. an action taken for the purpose of observing or measuring its results.
