### Syntax Rules for Calling the Loader

Note the following general syntax rules when you call the Loader.

● Case-sensitivity
There is no distinction between upper- and lower-case letters. The Loader converts all names to upper-case characters internally, unless you place character strings in double quotation marks.

● Keywords
Both the keywords of the Loader and the SQL keywords can be used to denote database objects if they are placed in single or double quotation marks.

This documentation contains only a short summary of the functions of the script languages that can be used in the Loader. For more information, see the vendor documentation for Perl, Python, or Java.
