6.3.5 Usage of brackets

In SINGULAR, curly brackets ({ }) must always be used to enclose the statement body following such constructs like if, else, for, or while, even if this block consists of only a single statement. Similarly, in the return statement of a procedure, parentheses (( )) must always be used to enclose the return value. Even if there is no value to return, parentheses have to be used after a return statement (i.e., return();). For example,

 
if (i == 1) return i;    // WRONG!!!!!

results in an error. Instead, it must be written as

 
if (i == 1) { return (i); }.
