As far as I can tell, UE doesn't support the {min,max} RE format, so there is no easy way to do this. You could, of course, do a find with RE "^...<133 dots>....+", but that's a pain. (It would really have to be 133 dots in a row!)
You could do it in a macro with something like this:
InsertMode
ColumnModeOff
HexOff
UnixReOff
top
Loop
Key RIGHT ARROW
Key END
IfColNumGt 132
ExitLoop
EndIf
IfEof
ExitLoop
EndIf
EndLoop
(Note that this assumes you don't have the option checked to allow positioning beyond line end.)
This would find the first line with more than 132 characters in it in the current file. You could then wrap it in a macro to try all open files. But this isn't very elegant either.
