Additionally a person should be able to trim spaces off of the beginning and end of a string as well as convert the case to all upper or all lower.


			=== Programming and Software Development ===

			The person should demonstrate basic skills in maintaining and updating a code base. The names of the scripts should indicate what they do and be consistent for a project. Backups of the codes should be maintained, and the person should be able to demonstrate that they can compare and find the difference between files.

			Most importantly the person should demonstrate consistent habits in commenting a script. Scripts should include comments that indicate what they do and how the programmer accomplishes each task within a script. Every event and subroutine also includes a block of comments to indicate which tasks it is used to complete.

			We do not specify which commenting style should be used, but the style should be consistent. The person should be familiar with using both the "//" and "/* ---- */" notations for creating comments. Codes that are submitted for the practicum will be evaluated for commenting as well as for function.

			At the basic level the person should be able to assign a key, know the memory costs, and have a basic idea of what a key is. The person should be able to demonstrate how to assign a key and how to compare keys.

			Additionally, the person should know about the predefined variables such as NULL_KEY, TEXTURE_BLANK, TEXTURE_MEDIA, TEXTURE_DEFAULT, TEXTURE_PLYWOOD, and TEXTURE_TRANSPARANT.

			==== Math Functions ====

			At the basic level the person should demonstrate an understanding of the difference between variables of type integer and float and the operators for each type. The person should also be able to demonstrate an understanding of the various boolean operations and how they differ from the integer operations.

			===== Integer Functions =====

			The person should be able to demonstrate a knowledge and an understanding of the basic operations. This includes the operations given at [http://wiki.secondlife.com/wiki/LSL_Operators]. This includes the basic operations, modulus operation, and various assignment operators.

			This also includes the bit-wise operations. The person should be able to represent an integer in decimal, binary, and hexadecimal forms. Given a number in any of the forms the person should be able to demonstrate an understanding of each of the bit-wise operations and combinations of the bit-wise operations.

The person should know the difference between truncation and rounding (including rounding up and rounding down in consistent ways with both positive and negative floating point numbers). The person should demonstrate how to round and how to truncate using only the basic operations and casting numbers.

			===== Floating Point Operations =====

			In addition to the operations in the context of integers the person should also demonstrate an understanding of floating point numbers. This includes an understanding of the basic operations, but also includes the issues of rounding errors versus truncation errors in the context of floating point numbers. This also includes issues of the accumulation of errors which can lead to phenomena such as "prim drift."

	A person should know what position is in the context of SL. This means the person should know the difference between a global coordinate, an absolute position within a sim, and the local position within a ~~linkset~~. An understanding of the different contexts when you might use local versus absolute is vital to working with rotations and vectors. For example, when working within a ~~linkset~~ a local coordinate system is used. At the same time it is not uncommon to make use of local offsets when dealing with two separate objects.
