Using this UDDF feature, it is possible to easily set up definitions for the generation of dive tables. Afterwards, for example different programs may calculate such a table. Then these tables may be compared with each other.

Maximale Grundzeit in Minuten bei verschiedenen Flaschenvolumina,
Tauchtiefen und Atemminutenvolumen (AMV)
unter Beruecksichtigung von notwendigen Dekompressionsstopps
Wird die Nullzeit bei einem Tauchgang ueberschritten, so wird der
max. Grundzeit ein "d" (fuer Deko-Tauchgang) vorangestellt.
Ist die maximale Grundzeit laenger als die Nullzeit, aber dafuer
in der Tabelle kein Dekostopp angegeben, so wird die Nullzeit als
maximale Grundzeit angegeben und dieser ein "s" (fuer "Sicher-
heitsstopp") vorangestellt. In diesem Fall obliegt es dem Taucher,
einen Sicherheitsstopp von z.B. 3 min auf 5 m (oder laenger) zu machen.
Muss die maximale Grundzeit auf die laengste in der Tabelle enthaltene
Grundzeit gesetzt werden (weil fuer laengere Grundzeiten keine
Dekostopps mehr berechnet wurden), wird dem Wert ein "t"
vorangestellt. In diesem Fall ist die theoretisch moegliche maximale
Grundzeit laenger als die angegebene, aber dafuer existieren keine
