3.5.6 Flow control

A block is a sequence of commands surrounded by { and }.
 
{
   command;
   ...
}
Blocks are used whenever SINGULAR is used as a structured programming language. The if and else structures allow conditional execution of blocks (see if, else). for and while loops are available for a repeated execution of blocks (see for, while). In procedure definitions, the main part and the example section are blocks as well(see proc).
