ALLBOND

Function

ALLBOND is used to specify that all bonds in the search fragment must be either cyclic or acyclic.

Example

Suppose we have built the fragment (i) - see below.

If we conducted a search with the above specification, viz. ALLBOND C, then a hit would be registered for the apomorphine derivative (ii) but no hit would be registered for the adrenalone derivative (iii).

The ALLBOND option toggles with respect to 3 settings:

The toggle process is analogous to that described for the CYCLICITY command.
