[gradsusr] How to create a new Grads file?

[Celso Bandeira de Melo Ribeiro]

Dear Grads user,
I need a help.
I'm trying to generate monthly rainfall files by accumulating daily
rainfall from TRMM-MERGE.
I created an scripts in this Grads and it is adding precipitation well for
each month, but don't know how can I save this result, the monthly sum in a
new Grads file.
Could someone help me to save the monthly rainfall data in a new Grads
file?
Here the code I'm using in Grads.

'open pcp.ctl'
'jan = sum(prec,t=1,t=31)'
'fev = sum(prec,t=32,t=59)'
'mar = sum(prec,t=60,t=90)'
'abr = sum(prec,t=91,t=120)'
'mai = sum(prec,t=121,t=151)'
'jun = sum(prec,t=152,t=181)'
'jul = sum(prec,t=182,t=212)'
'ago = sum(prec,t=213,t=243)'
'sep = sum(prec,t=244,t=273)'
'oct = sum(prec,t=274,t=304)'
'nov = sum(prec,t=305,t=334)'
'dec = sum(prec,t=335,t=365)'
'd jan'

I would like to save each monthly file: jan, fev, mar,...,dec.

Best,
Celso
