This manual explains the procedure concept in SDF-P as well as describing all SDF-P interfaces and the creation of S procedures. Although the manual does not deal with the rules applicable to non-S procedures, the behavior of non-S procedures is described where incompatibilities between S and non-S procedures need to be taken into account.
