According to the manual:

"You can specify the optional reserved word *LOCK. When *LOCK is specified, the
data area remains locked after it is updated. When *LOCK is not specified, the
data area is unlocked after it is updated."

>      ?* set receipt number
>      c     *lock         in        rec#dta
>      c                   eval      rec#dta = rec#dta + 1
>      c                   eval      precpt# = rec#dta
>      c                   out       rec#dta 
> There can be mulitple versions of this program at any given

> receipts) and it seems that if both programs hit this the

> 1. On the OUT opcode, does it automatically release the 
> locks?  Or should 
> I be using the UNLOCK opcode as well?
> 2. Can I use lock logic here like record lock logic that RPG has?
