5.3.2 Instructions
Instruction
An instruction consists of several reserved command words, identifiers and operators and is at the
end terminated by the end of the line. 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. By use of the "_"
character (low dash) it is possible to extend the instruction into the next line.
If a= 5 _ ' instruction across two lines
a=a+ 10
It is also possible to place more than one instruction into the same line. The ":" character (colon)
will then separate the individual instructions. For reason of better readability however this option
should rather seldom be used.
a= 1 : b= 2 : c= 3

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 a single quotation mark and end up at the line’s end.
· Multi line commentaries start with " /* " and end up with " */ ".
