<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Good Evening All,<br>
<br>
I am trying to implement a while loop that will automatically insert each forecast hour (ex. 000, 003, 006, etc) of many control files for a weather model directly into the 'open .ctl' line.<br>
<div><br>
The reason for this is because I have 10+ control files that I'd like to run sequentially without having to create 10 different GrADS scripts to process each individual control file.<br>
<br>
What I have in place now does not return any errors within GrADS but, it doesn't process anything and the screen stays black. Clearly, I'm doing something wrong...<br>
<br>
In UNIX, you can simply use printf "%0*d\n" to accomplish three leading zeros. I've tried modifying this process by putting a "!" in front of printf to run the process outside of GrADS but, this doesn't seem to be working...<br>
<br>
I've attached the "working" script to this email in hopes that someone who is more GrADS-savy than me can take a look at the coding and potentially figure out this issue for me.<br>
