Do you have to only output a single variable to each binary data file? I could see the utility of this to create line graphs within GrADS from text data. <BR>

Before GrADS can handle your data, you need to convert it from text to binary. Try something like this: <BR>
<BR>
</SPAN></FONT><FONT SIZE="1"><FONT FACE="Courier, Courier New"><SPAN STYLE='font-size:9pt'>'open dummy.ctl'<BR>
file=7hA01.out.txt<BR>
nlinesinfile=755<BR>
i=1<BR>
'set gxout fwrite'<BR>
'set fwrite 7hA01.out.bin'<BR>
while (i<=nlinesinfile)<BR>
res = read(file)<BR>
line2=sublin(res,2)<BR>
val = subwrd(line2,2)<BR>
'd 'val<BR>
i=i+1<BR>
endwhile<BR>
'disable fwrite'<BR>
</SPAN></FONT></FONT><FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'><BR>
...dummy.ctl looks like this:<BR>
<BR>
</SPAN></FONT><FONT SIZE="1"><FONT FACE="Courier, Courier New"><SPAN STYLE='font-size:9pt'>dset foo<BR>
