LEN
Chapter 2 Program Instructions
Field of Application Function returning the number of character positions in a string.
Syntax LEN()
is the string from which the number of characters will be
returned.
Remarks The number of characters to be returned includes unprintable characters, but
the quotation marks enclosing the string expression are not included.
Examples In this example, lines 40 and 50 illustrate two ways of using the LEN function,
when the number of characters from several string expressions are to be
added up.
10 A$="INTERMEC" (8 char.)
20 B$="THERMAL" (7 char.)
30 C$="PRINTERS" (8 char.)
40 PRINT LEN(A$+B$+C$)
50
RUN

PRINT LEN(A$)+LEN(B$)+LEN(C$)
yields:
This example illustrates that unprintable characters, e.g. space characters,
are included in the value returned by the LEN function:
PRINT LEN("INTERMEC THERMAL PRINTERS")
yields:
