lock screen question and detect field question

[Sean Cole (Pi)]

Hi Larry,

As well as the afore mentioned, all excellent comments, you can use the 'if
exists(fld "myField01") then' script. I also encapsulate all sorts of
things in "try"..."end try" commands. These are extremely powerful although
could be considered a little lazy. For example, when using iPhone commands
I sometimes lazily put them inside "try"s in an effort to prevent them
causing a problem when testing on the desktop. So, "try ¬ delete field
myField01 ¬ end try" does not cause a lasting problem. Using a Catch pError
inside the try will help out if you need to detect if it has been
deleted/exists or not.

All the best
