What's with the ALL_CAPS in vb3? What does HTML_SELECTED do?

[dwh]

I'm seeing words in all CAPS treated as variables. Sorta kinda. What does it do?

If you set HTML_SELECTED somewhere, even in the evaluation side of theequation, can it be used again. This is another one of those things invb3 that confuses the hell out of me.

[Andreas]

Those are not variables but constants.

HTML_SELECTED is selected="selected", or TABLE_PREFIX is your table prefix (as defined in config.php), TIMENOW is the time the script was started, and so on.

[dwh]

Is there one place where all constants are defined? (I guess not since I don't remember too many things defined there.)

[Andreas]

No. There are constants in many files.

[Marco van Herwaarden]

And don't even search all files for the definition of some constants. Bitmask permission constants for example are generated dynamic in the init phase of all scripts.
