[SAC-HELP] how to set the LOVROK to be TURE?

[Liping Fan]

Hi everybody,

 

I am trying to write over one sac file, but the LOVROK is FALSE. When I try
to use 

"r $sac_file; chnhdr LOVROK TURE; write append .OK"

or 

"r $sac_file; chnhdr LOVROK 1; write append .OK",

they both don't work.

 

Does anybody know why?

 

Thanks in advance!
