2.3.3 Remarks
The blocks in a program can be explained by means of remarks. A remark permits instructions
for the operator to be displayed on the screen.
With remarks, the following must be noted:
• The remark must be enclosed in round brackets.
• A space (blank) must be provided between the opening bracket and the start of the remark
as well as between the end of the remark and the closing bracket.
• No percentage characters "%", end-of-block characters "
L
F
", or additional brackets "()"
are permitted within the remark.
• The remark must not be located between the address and a digit or between a word and
the associated parameter.
• The remark can be up to 120 characters long. A maximum of 41 characters are shown on
the screen in the comments line.
• It is advisable to write the remark at the end of the block or in a separate line.

2.4 Word format
A word is an element of a block. It comprises an address character and a string of digits. The
address character is normally a letter. The string of digits can include signs and decimal
points. A sign is written between the address letters and the string of digits. A positive sign can
be omitted.
