Character
Alphabetical characters, numbers, symbols, and the special marks below can be used as characters. Lower
case alphabetical characters are only recognized as lower case when enclosed by double quotation marks
("). Lower case and upper case are not distinguished anywhere else. With the exception of text enclosed by
double quotations (") and comments described below, use only half-width alphanumeric characters and half-
width symbols.
Line
A unit that is composed of a line number and a statement is called a line. Blank lines and lines that are only
comments are acceptable in a program. Multiple statements (multi-statement) can also be written on one line.
When writing multiple statements, separate each statement with a colon (:).
Line number
The number that is automatically assigned to each line when a program is loaded in the FH/FZ5 system is
called a line number. Line numbers are mainly used during program debugging to identify the locations of
errors. Do not write line numbers when creating a program.
