4.2.2 Instructions

Instruction

An instruction consists of several reserved command words, identifiers and operators and is at the

end terminated by a semicolon (';'). In order to separate various elements of an instruction there are

spaces in between the instruction elements which are called "Whitespaces". By “spaces“ space

characters, tabulators and line feeds ("C/R and LF") are meant. It is of no consequence whether a

space is built by one or several "Whitespaces".

Simple Instruction:

a= 5;

An instruction does not necessarily have to completely stand in one line. Since line feeds do

also belong to the space category it is legitimate to separate an instruction across several lines.

if(a==5) // instruction across 2 lines

a=a+10;

Instruction Block

Several instructions can be grouped into a block. Here the block is opened by a left tailed bracket

("{"), followed by the instructions and closed at the end by a right tailed bracket ("}"). A block does

not necessarily have to be terminated by a semicolon. I. e., if a block builds the end of an instruction

then the last character in the instruction will be the right tailed bracket.

if(a>5)

{

a=a+1; // instruction block

b=a+2;

}

Comments

There are two types of commentaries, which are the single line and the multi line commentaries. The

text within commentaries is ignored by the Compiler.

Single line commentaries start with "//" and end up at the line’s end.

Multi line commentaries start with "/*" and end up with "*/".

/* a

commentary */

// a single line commentary
