Hi.
I have two questions about the SIGMAtoP of the latest regcm3(2006).
At first,I do SIGMAtoP in Input.In Input directory I found SIGMAtoP.f file in tools directory.so I copy /icbc/tools/SIGMAtoP.f to /icbc/, and change three lines as following:
include '../PreProc/ICBC/icbc.param'
data fn/'ICBC2000100100'/
data fz/'IC_P2000100100'/

Then I do "pgf90 -byteswapio -o SIGMAtoP SIGMAtoP.f"and "./SIGMAtoP",but there is a error
"PGF90-S-0038-Symbol, iomega, has not been explicitly declared (SIGMAtoP.f)
0 inform, 0 warnings, 1 severes, 0 fatal for MAIN"
and the file IC_P2000100100 is not produced.What's the problem?

When I do SIGMAtoP in output,there is another problem.There I copy /Commons/tools/SIGMAtoP.f to output directory,edit SIGMAtoP.f, and make sure the parameters setting and ATM files name are the right one.
       jx ! number of points from west to east
       ix ! number of points from south to north
       kx ! number of vertical levels of SIGMA
       np ! number of vertical levels of P
       nfile ! how many ATM.yyyymmddhh files you have
       inout ! file name of ATM
       number ! how many time slices in your ATM.yyyymmddhh file
then
    pgf90 -byteswapio -o SIGMAtoP SIGMAtoP.f
    ./SIGMAtoP
but PLEV_VAR file is not produced,and then the PLEV_VAR.ctl file can not be
opened by Grads.
