Single Value Transforms
A number of keywords fall into the class of Single Value Transforms. These
have initial and final stack requirements as shown in Figure 24-1.
Single value transforms can operate on a numeric value, or the address of a
value (a variable), or on an array of values. Table 24-2 lists some examples.
Two Value Transforms
Some LPL keywords are Two Value Transforms, and their stack require-
ments are shown in Figure 24-2
Table 24-2. Examples using
ABS
, a single value transform.
LPL Code Result
-12 ABS Puts 12 (LONG) on the stack
48.4 ABS Puts 48.4 (DOUBLE) on the stack.
arr1 ABS Sets every element of arr1 to its absolute
value.
