Then you can use the same kind of thing I already showed you - read in
the lines of the file as a strarr, then use where, stregex, and
value_locate to pick out the lines with '=' in them and associate each
line with an equals sign, then concatenate the lines using strjoin,
then use strsplit to turn the long string into an array.
