I also re-did the M&A queries, pulling more info from 1980 to 2020H1 in four goes.

Normalizing the files is generally straight-forward. Use NormalizeFixedWidth.pl (see [[Normalizer Documentation]]) and only copy down the missing keys (e.g., coname, statecode, datefirst, etc.). For most files there is nothing to fix, just select the last header row and go. For fund fix the header first, so that the capital under management header entry has some space after it. For RoundOnOneLine, remove the footer, run NormalizeFixedWidth.pl first then RoundOnOneLine.pl, and then fix the header. For fund, fund execs, and portco, remove double quotes after normalization.
For PortCoLongDescription (see [[Vcdb4#Long_Description]]):
