Our published read_date_file with the /vstruct keyword does not read
this file.
x=read_data_file('file.txt',/vstruct)

I missed to include first column of text type. I have fixed this in our
working library. Now I am testing the whole thing.

help,x.data,/str
** Structure <83892dc>, 3 tags, length=20, data length=20, refs=2:
VAR0 STRING 'abc'
VAR1 FLOAT 1.00000
VAR2 FLOAT 2.00000

help,x.data[1],/str
** Structure <83892dc>, 3 tags, length=20, data length=20, refs=2:
VAR0 STRING 'def'
VAR1 FLOAT 3.00000
VAR2 FLOAT 4.50000

help,x.data[2],/str
** Structure <83892dc>, 3 tags, length=20, data length=20, refs=2:
VAR0 STRING 'ghij'
VAR1 FLOAT 2.30000
VAR2 FLOAT 23.4400

If you are interested I can sent a separate copy of the changed files.
