I am trying this<br>
<br>
draw title Precip diff (mm/d), Model`bRef2`n - Model`bRBS2`n<br>
<br>
it is should write as below<o:p></o:p></p>
<p style="margin-bottom: 0.0001pt;">Precip diff (mm/d), Model<sub>Ref2</sub>
- Model<sub>RBS2</sub><o:p></o:p></p>
<p style="margin-bottom: 12pt;">But this is not working in my
shell script (K-Shell) whereas when I am trying the same in a
gs file it is working perfectly....<br>
Can any one suggest me how to use supper and sub script
commands in shell scripts!!!<br>
