header by a white space. In the response to a query, the short form of the text is provi-

Response: LAND
Character Strings
Always enter strings in quotation marks (' or ").
Example:
HCOP:ITEM:LABel "Test1"

Block Data
Block data is a format which is suitable for the transmission of large amounts of data.
For example, a command using a block data parameter has the following structure:
FORMat:READings:DATA #45168xxxxxxxx
The ASCII character # introduces the data block. The next number indicates how many
of the following digits describe the length of the data block. In the example, the 4 fol-
lowing digits indicate the length to be 5168 bytes. The data bytes follow. During the
transmission of these data bytes all end or other control signs are ignored until all
bytes are transmitted.
#0 specifies a data block of indefinite length. The use of the indefinite format requires a
NL^END message to terminate the data block. This format is useful when the length of
the transmission is not known or if speed or other considerations prevent segmentation
of the data into blocks of definite length.
D.1.3.4 Overview of Syntax Elements
The following tables provide an overview of the syntax elements and special charac-
ters.
