[gradsusr] combine multiple variables in a single text file

[Anil acharya]

Hi
I am using write instead of print and want two parameters in the same file (formatted: 1st column as pcp, 2nd column as tmp). But I am getting some format error. Can you tell me what is wrong in the last line of the script?
(This format is similar to matlab). 

'set gxout print'
'set lat 38 42'
'set lon -105 -96'
'd apcp'
pcp=subwrd(result,16)
'd tmpsfc'
tmp=subwrd(result,16)
dummy = write('output.txt', '%8.4f %8.4f', pcp, tmp)

 
Please let me know if there is some other way of formatting multiple variables in a text file using write command.
Anil

I am not sure what is your problem, regridding or writing data to text files. For text files, are you familiar with these recipes?
