ENUM

ENUM is a CAOS command which controls flow.

Usage
Syntax: ENUM family (int) genus (int) species (int)

This marks the start of an enumeration loop, which must be ended by NEXT. It cycles through every agent which matches the classifier: first setting TARG, then evaluating the content of the loop, then going on to the next agent, and so on until all agents of the given class number have been exhausted.

Any or all of the arguments may be 0, which is a wildcard. So ENUM 0 0 0 will loop through all agents.

At the end of the loop, TARG is set to OWNR - so store the original TARG somewhere else if it's important.

Example
Destroy all badbugs: ENUM 2 14 0 KILL TARG NEXT

Limit elasticity of all toys: ENUM 2 21 0 DOIF ELAS gt 50 ELAS 50 ENDI NEXT

Age all creatures to adult: ENUM 4 0 0 SETV va00 4 SUBV va00 CAGE DOIF va00 gt 0 AGES va00 ENDI NEXT

Show the bounding boxes of everything: ENUM 0 0 0 DCOR 1 NEXT
