Hello All,
Can someone show me the alternatives using public variable.
I have used them extensively in my application but i hear it can get really dangerous.

I have used public for the ff;

1. At the main program (startup) to retrieve some table
values into memory to be used throughout the program without opening the table all the time. I have read about \DEFINE. Can this work for retriving table values?

2. Arrays deinitions - to prevent the erroy message 'array does not exist'


PS. May i also know what the real dangers with public variables are?

TIA
