File headers provide metadata that describe the data in the file. A TOA5 header
contains the metadata described below. Other data formats contain similar

modelname,CR800serialnumber,OSversion,CRBasicprogramname,
programsignature,data‐tablename.
Line 2 – Data-Field Names
Liststhenameofindividualdatafields.Ifthefieldisanelementofan
array,thenamewillbefollowedbyacomm
a‐separatedlistof
subscriptswithinparenthesesthatidentifiesthearrayindex.For
example,avariablenamed“values”thatisdeclaredasatwo‐by‐two
array,i.e.,
Public Values(2,2)
willberepresentedbyfourfieldnames:“values(1,1)”,“values(1,2)”,
