Station data Input

[TRINA BOSE]

Hi Jenifer

Tried your suggestion...

ga-> set x 1
LON set to 1 1
ga-> set y 1
LAT set to 1 1
ga-> set t 1 540
Time values set: 1960:1:1:0 2004:12:1:0
ga-> d o18(STID=4218200)
No stations to plot
ga-> d t(stid=4218200)
Syntax Error:  Invalid Operand
  't' not a variable or function name
  Error ocurred at column 1
DISPLAY error:  Invalid expression
  Expression = t(stid=4218200)
ga-> d o18(stid=4218200)
No stations to plot


Trina

PS: Does the stid needs to be alphabets/alphanumeric?
