; WLF file size limit. Limit WLF file size, as closely as possible,

[msg_system]
; Change a message severity or suppress a message.

; fatal = 3016,3033
; suppress = 3009,3016,3043
; The command verror <msg number> can be used to get the complete
; description of a message.
; Control transcripting of elaboration/runtime messages.
; The default is to have messages appear in the transcript and
; recorded in the wlf file (messages that are recorded in the
; wlf file can be viewed in the MsgViewer). The other settings
; are to send messages only to the transcript or only to the
; wlf file. The valid values are
; both {default}
; tran {transcript only}
; wlf {wlf file only}
