[gradsusr] opening text file data

[Zablone Owiti]

James, 

 You cannot open the  7hA0.out.bin file directly as you attempted. You need to open it  via a Control file that was done by Jennifer. The control file is:
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

Hi, 

sorry I took long to answer. Thank you all for your help

Jennifer, I have copied the first script you wrote into a script.gs, and the second into a dummy.ctl
Then I opened grads and ran script.gs and got the following error:

Warning: OPTIONS keyword "template" is used, but the
   DSET entry contains no substitution templates.

Then I changed the contents of dummy.ctl to the third set and ran script.gs and I obtained 7hA01.out.bin
However when I tried using open with grads I got the following error

ga-> open 7hA01.out.bin
Scanning description file:  7hA01.out.bin
Open Error:  Unknown keyword in description file
  --> The invalid description file record is:
  --> o-ER`0Ej.Eá¦3E=E3;E;E5:E{7E¤ø1E\31Eá0Eáº+Eͼ+EÍL5E2E)<9Eu;Eׯ;Eq)<EH=EÉ2E
û9EìY1E¤¨2E-Eq¥/E\[6Ef6Eìq9Ef¦;E)ô=E
  The data file was not opened.

James
