Case Sensitivity

 

Source code in the source files as well as in the form files is not case sensitive. The capitalization of the keywords is done for easier code reading and is not obligatory.

In the literal character strings enclosed in single or double quotation marks the letter case is preserved. The character string can be used as character literals, file names, etc. If you work on Linux, you may want to preserve the letter case in the file names. In all other cases the strings that are not enclosed in quotation marks are switched to lower case during compilation. For example, in a variable name consisting of lower and upper case letters all the upper case letters will be turned to lower case letters during compilation.
