Hi! Arlindo,
I am getting the same error as reported above "Syntax Error: Invalid
Operand 're' not a variable or function name".
I am using GrDAS *2.0.a9.oga.1 version on Windows XP. *I have attached the
output of q udx in my previous reply as you had posted for the ouput of q
config and q udx in this e-mail chain.
What changes I need to make as the changes you have suggested are for LINUX
OS.
Thanks,
Subash
