0x0074 Reach/Put
Op9 Bit 4 - Use Reach Anims
Operand 9, bit 4 appears to force the "grasp" animation to use the entry from the STR# 0x92 "Reach Anims" resource and not the usual 0x81/0x82 "Anims - Adult/Child" (et al) resources.
See the BHAVs "Chess - Reach for Piece", "Phone - Hang Up Wall", "Phone - Hang Up Table", "Read - Get Book From Floor", "Interaction - Smash" (from Urn Globals), etc.
Hope these notes are of use to someone. Enjoy!
