All,
I need to know how to clear all error message that idl generated.
I am using this two lines to stop to trap my error.
Help, /Last_Message, Output=theErrorMessage
errorLength = N_ELEMENTS(theErrorMessage)
However, I need to clear all the error message so that when I am
looping to these two lines again the
errorLength should be zero when no error message occur.
Thanks

i try that too and it didn't work because the "Warning" message is
looping within the mrd_hread.
I might have to try modify the mrd_hread procedure as you have
suggested.
procedure
