4.3.2 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 "_" char-

acter (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

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 a single quotation mark and end up at the line’s end.

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

/* a

multi line

commentary */

' a single line commentary

Identifier

Identifiers are the names of Functions or Variables.

Valid characters are letters (A-Z,a-z), numbers (0-9) and the low dash ('_')

An identifier always starts with a letter

Upper and lower case writings are differentiated

Reserved Words are not allowed as identifiers

The length of an identifier is unlimited
