Rewrite Statements

The Rewrite statements are: expressions, assignments, conditional statements and return statements. A statement is terminated by semicolon.

Expressions

An expression is:

Type coercion

The type coercion is like a type cast in C. Its syntax is 

    `(' type `)' ident

the result of type coercion is as follows:

of the integer number (either decimal, octal or hex) it is converted to the integer, otherwise the result of the conversion is undefined.
type Variable type Resulting conversion
integer integer No conversion. This results in the same integer value.
integer string If the string value of the variable is a valid ASCII representation
string integer The ASCII representation (in decimal) of the integer number.
string string No conversion. This results in the same string value.

Assignment

An assignment is: 

    ident = expression ;

The variable ident is assigned the value of expression.

Function calls

These take the form: 

    ident ( arg-list )

where ident is the identifier representing the function, arg-list is a comma-separated list of expressions supplying actual arguments to the function. The function ident references can be either a compiled function or a built-in function.

Please note that, unlike in C, the mismatch between the number of actual arguments and number of formal parameters in the compiled function declaration is not an error but rather a warning.
