The MINI-L Source Code Language

MINI-L Language Description

The MINI-L language provides the following program constructs.

1. Integer scalar variables.
2. One-dimensional arrays of integers.
3. Assignment statements.
4. While and Do-While loops.
5. Continue statement.
6. Break statement.
7. If-then-else statements.
8. Read and write statements.
9. Comments.
10. Functions.

Here are some additional details of the MINI-L language.

• A comment is introduced by "##" and extends to the end of the current line.
• MINI-L is case sensitive. All reserved words are expressed in lower case.
• A valid identifier must begin with a letter, may be followed by additional letters, digits, or underscores, and cannot end in an underscore.
• Whitespace in MINI-L programs can occur due to regular blank spaces, tabs, or newlines.

Functions in MINI-L take some constant number of scalar arguments, and return a single scalar result. All arguments are passed by value (there are no reference arguments). A syntactically and semantically valid MINI-L program must contain a function named main, which takes no arguments and returns no result (the main function is unique in this regard).

The detailed syntax for the MINI-L language is described here. Since you will be designing your own custom programming language, your syntax will be different than the one provide in the syntax diagram. However, you may borrow ideas from this syntax diagram. The following table lists the precedence and associativity of all the operators in the MINI-L languages. Operators are listed top to bottom, in descending precedence.

MINI-L Example Programs

• math.min
• array.min
• ifelsetest.min
• loop.min
• function.min
• break.min
