The alphabet in programming languages

Question

Our task is to, for each letter of the (English) alphabet, write a program that prints the alphabet, in a language whose name starts with that letter.

Input: none

Output:

abcdefghijklmnopqrstuvwxyz

(trailing newline optional)

Rules:

• The scoring metric is the length of the programming language name, plus the length of the code. Hence, C will be assessed a "penalty" of 1, while GolfScript will be assessed a penalty of 10.
• One language/implementation per answer. Multiple answers are encouraged.
• The programming language should have existed prior to the writing of this post, on this eighteenth of April 2011.
• If a programming language name's first letter is not an English letter, it should not be coerced into one. It will be treated as a separate letter (meaning less competition).
• No answer will be accepted until every English letter has a solution.

Answer 6

A is for APL, 14 chars -> score = 17

All code works in at least NARS2000, it uses system specific functions, so it may not work on your APL distro.

If Lower case is necessary:

1601⎕dr⍉96+⍳26

Or in ascii rendering:

1601{Quad}dr{CircleSlope}96+{Iota}26

Explanation, from right to left:

1. construct an array from 1 to 26
2. add 96
3. reverse coordinates (to convert to a normal array instead of an Arithmetic Progression Arrays
4. convert data to character

If uppercase is permissible only 2 chars ;) :

⎕a

or in ascii rendering:

{Quad}a

Answer 7

P is (actually) for Piet - 57 codels

Large version (codel size = 6)

Small version (codel size = 1)

Tested with Erik's piet interpreter npiet and developed with Piet Creator.

Edit: Here is a "trace" version (generated with npiet -tpf) so you can see how it works.

Execution starts in the top left and goes around the border clockwise. The top edge and right edge are setup (calculating the value of a (97) takes quite a few codels). The loop starts on the bottom edge and goes to the left edge. When the value of z is reached the program turns right into the cross section under the first P and terminates.
