| [224] | 24 | ;QUESTION: How do I make an IDL variable have a type "undefined"? |

| [242] | 25 | ;ANSWER: At the main IDL level you can use the IDL procedure <proidl>DELVAR</proidl> to |
|---|
| [2] | 26 | ;delete an IDL variable and make it undefined. Inside of procedures |
|---|
| [258] | 27 | ;and functions, I use this little program named <pro>undefine</pro> that I got |
|---|
| [2] | 28 | ;from Andrew Cool at the DSTO High Frequency Radar Division in |
