The error is caused by the space in the filename. You can fix this with a name expression

m.tcIndexCmd = "INDEX ON  UPPER( mirror.cnomres ) TAG COLUMN1 OF ('C:\CDBK90\AMLINE\CRYSTALDATA\SERVER2008 # BHT44\MIRROR.CDX') DESCENDING ADDITIVE"

BTW, why do you need the "of ...cdx"? I usually add the index tags to a structural index, and leave it there.
