In fixed format, data structure includes one or more lines specifying the attribute, line number, starting position on the line (counting from 1), and field width. For example:
@istructure tag, 1, 1, 12
@istructure pointsource, 1, 14, 1
@istructure pointtype, 1, 19, 7

SINUSOID R FLOAT32
NEXTPOINT Lab FLOAT16
The lines starting with the asterisk (*) are comment lines and are ignored. Their only purpose is to improve readability. You can change the comment character (Change the comment character).
The format lines come first and are all grouped together. This defines a record. If there are more data lines than are specified in the record, piconfig interprets these as additional records of the same format.
Fixed format is also used in the OpenVMS PI System PIDIFF utility.
