IG determines the overall structure of a line by examining the source before
any evaluation bracket processing occurs. This precludes lines that begin
with an evaluation bracket expression that resolves to a generator line (e.g.,
starts with a %%). The following line (line linenumber from source file
filename) is assumed to resolve to a text line to be output. Suppress this
message with the ERROPT=(NOEVALSTARTLINE) command line parameter.
