-100
Command error
This is a generic syntax error for devices that cannot
detect more specific errors. The code indicates only that
a command error as defined in IEE 488.2, 11.5.1.1.4 has
occurred.
-110
Command header error
An error was detected in the header. This message is
used when the device cannot detect the more specific
errors described for errors -111 through -119.
-104
Data type error
The parser recognized a data element that is not
allowed. For example, numeric or string data was
expected, but block data was encountered.
-123
Exponent too large
The magnitude of an exponent was greater than 32000
(see IEEE 488.2, 7.7.2.4.1).
-170
Expression data error
This error, as well as errors -171 through -179, are
generated when parsing an expression data element.
This particular error message is used if the device
cannot detect a more specific error.
-178
Expression data not allowed
A legal expression data was encountered, but was not
allowed by the device at this point in parsing.
-105
GET not allowed
A Group Execute Trigger was received within a
program message (see IEEE 488.2, 7.7). Correct the
HP-IB controller program so that the GET does not
occur within a line of HP-IB program code.
-111
Header separator error
A character which is not a legal header separator was
encountered while parsing the header.
