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. Foreach loops.
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).

MINI-L supports foreach loops. These loops iterate over an array, executing the body of the loop with a specified variable bound to each of the array elements in turn.

The detailed syntax for the MINI-L language is described here. 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.
