Syntax
dexpr int l = lengthOfPrev(p, a ,pVal [,absVal]); where: int pVal; int absVal;
Description
This
function returns an integer expression that represents the length
of the interval variable that is previous to interval a in
sequence variable p. When interval a is present and is the first interval of sequence p, the function returns the constant integer value nVal. When interval a is
absent, the function returns the constant integer value absVal.
If the value absVal is omitted, it is considered
to be 0.
