- A program in TINY has a very simple structure:
- it is just a sequence of statements separated by semicolons.
- There are no procedures and no declarations.
- All variables are integer variables, and variables are declared simply by assigning values to them.
- There are only two control statements:
- an if-statement and a repeat-statement.
- Both control statements may themselves contain statement sequences.
- An if-statement has an optional else part and must be terminated by the keyword end.
- There are also read and write statements that perform input/output.
- Comments are allowed within curly brackets; comments cannot be nested.
- Expressions in TINY are also limited to Boolean and integer arithmetic expressions.
- A Boolean expression consists of a comparison of two arithmetic expressions using either of the two comparison operators < and =.
- An arithmetic expression may involve integer constants, variables, parentheses, and any of the four integer operators
+,-,*and/(integer division), with the usual mathematical properties. - Boolean expressions may appear only as tests in control statements-there are no Boolean variables, assignment, or I/O.
