A user recently queried the presence of records having the .DAT extension (EG LHVA.DAT) in the VERBS file and wondered what they were used for. They are used to pass information between the system and C routines. Rather than pass a large string of parameters to a C subroutine it is more efficient to pass a block of arguments as one variable which the C routine can put into memory and then treat as individual variables and pointers.
