  Thanks.
  I changed the script using math_int, as follows, but the similar error
message came.

'open anal_p.ctl'
'set lon 30 180'
'set lat -40 40'
'i0=ugrdsfc*2.+1.'
'd i0'
'd math_int(i0)'

Syntax Error:  Invalid Operand
   'math_int' not a variable or function name
   Error ocurred at column 1
DISPLAY error:  Invalid expression
   Expression = math_int(i0)
