OPAL: Language Basics Topic:
Definition of the Month: Camel Casing
Camel Casing capitalizes the first character of each word except the first word, so it frequently looks like a one or two hump camel. Used by many languages including Paradox's ObjectPAL. You can contrast Camel Casing with Pascal Casing which capitalizes the first character of each word (including acronyms over two letters in length) and was popularized by Pascal.

Paradox Tables Topic:
Question: What is the best way to copy my Paradox tables?

Answer:

What I recommend for our clients is to make sure no one is using the tables and then copy the entire folder. To make sure no-one is using the tables, check for .LCK lock files. If they exist, try deleting them. If you can delete them, then they were left over from an abandoned BDE session. Next, rename the folder to lock out users for the duration of the copy. Copy the folder, then rename the folder back.

To copy live tables, I suggest you write an application in Paradox, Delphi, etc. that uses the BDE copy table code. It's safe, effective, and you can build in error checking.

OPAL: Wicked Coding Tasks Topic:
Tip of the Month

You can speed up a TCursor in by using update(), setBatchOn(), or copyToArray(). If you use setBatchOn(), make sure to follow it with setBatchOff() every time you use it.
