Errors Assembling Schemes Using Signed Word And Signed Long Word Data
9 April 1997
Problem
An error in the logger assembler macro files can result in errors when assembling schemes that use signed word (16-bit) and signed long word (32-bit) data.
An example of signed word data is the Starflow Velocity channel. An example of signed long word data is the Starflow Totalised Flow channel (in the Flow Extension instrument).
Symptom
The following may appear when assembling a scheme that calculates minimums of signed long word (32-bit) data:
schemename.SR0(2) : error A1011: doubly defined label '@?1'
schemename.SR0(3) : error A1011: doubly defined label '@?1'
The following may appear when assembling schemes that compare signed word (16-bit) data (eg. referencing signed words in an event):
schemename.EVT(2) : error A1012: syntax error undefined variable '??0000'
for Starloggers, or for Macro loggers:
schemename.EVT(2) : error A1012: syntax error undefined variable 'op'
schemename.EVT(2) : error A1012: syntax error undefined variable 'op'
schemename.EVT(2) : error A1012: syntax error undefined variable 'op'
schemename.EVT(2) : error A1012: syntax error undefined variable 'op'
schemename.EVT(2) : error A1012: syntax error undefined variable 'ev'
schemename.EVT(2) : error A1012: syntax error undefined variable 'ev'
schemename.EVT(2) : error A1012: syntax error undefined variable 'ev'
schemename.EVT(2) : error A1012: syntax error undefined variable 'ev'
schemename.EVT(2) : error A1012: syntax error undefined variable '?1'
schemename.EVT(2) : error A1012: syntax error undefined variable 'b'
schemename.EVT(2) : error A1012: syntax error undefined variable 'b'
schemename.EVT(2) : error A1012: syntax error undefined variable 'dst'
