Languages Focus: Case Sensitivity

Case sensitiviy in this case is referring to commands and variable names. For example, are "printf" and "PrintF" equivalent? Are fullname and FullName equivalent? When you create commands, operations, methods, or variables should you worry about case?

ObjectPAL Case Sensitivity

ObjectPAL is not case sensitive. My preference for ObjectPAL is to follow the camel casing promoted in the examples and help files originally developed by Borland.

Syntax Example:

All of the following are equivalent:

msgInfo "", "Hello"
MsgInfo "", "Hello"
msginfo "", "Hello"
MSGINFO "", "Hello"

Variables are not case sensitive.

Var
FullName String
endVar
fullname="Mike Prestwood"
msgInfo("", fullNAME)
