Hi:
In principle, you can read include/link.h to get the 'record' pointer of a link, cast that to the appropriate type, ... But that's a bad idea because you'd directly access the memory of that other record without it being locked. Unless you really know what you're doing, it's much safer to use the standard `asub` (ex `genSub`) record and have its output links handle writing to other records.

Just wanna know that if we have a 'sub' record then from its subroutine can we directly write into RVAL field of some other records say 'ai' records in the same database.
If the answer is yes then how does one get the address/pointer of other records (ai for example) in the subroutine of 'sub' record ?
Thanks,
Stefen.
