[gradsusr] opening text file data

[Jennifer Adams]

James,
Before GrADS can handle your data, you need to convert it from text to  
binary. Try something like this:

'open dummy.ctl'
file=7hA01.out.txt
nlinesinfile=755
i=1
'set gxout fwrite'
'set fwrite 7hA01.out.bin'
while (i<=nlinesinfile)
  res = read(file)
  line2=sublin(res,2)
  val = subwrd(line2,2)
  'd 'val
  i=i+1
endwhile
'disable fwrite'

...dummy.ctl looks like this:

dset foo
options template
undef -9.99e8
xdef 1 linear 1 1
ydef 1 linear 1 1
zdef 1 linear 1 1
tdef 755 linear 0Z01JAN1948 1mo
vars 1
foo 0 99 foo
endvars

... and your new GrADS data set looks like this:

dset ^7hA01.out.bin
undef -9.99e8
xdef 1 linear 1 1
ydef 1 linear 1 1
zdef 1 linear 1 1
tdef 755 linear 0Z01JAN1948 1mo
vars 1
var 0 99 var
endvars
