Variable Naming Standards In PowerBuilder
Variable naming standards for standard variables declared within the Powerscript environment. This includes variables declared in dialog windows such as global and instance variables. The object name should be typed using Camel Case. Camel case is a standard used to aid readability in scripts, the first letter of each new word in the variable name should be in upper case. The scope and prefix should always be in lower case
