Below is content of attached data file
Of course trying to open it generates
using delimiter ','
longest line: 92 characters
first field: 'index'
number of columns = 6
number of variables: 6
number of non-blank lines: 2
scanning for variable names...
'ols' is a reserved word
For .csv I can easy change 'ols' anywhere
For .xls(x) I have LibreOffice if
I use Ubuntu, or if I do not want to be a pirate
How about stata, etc?
I think, gretl could change such names
I mean only reserved words: this would open
files that used to fail to be opened
So a new possibility and no backward-incompatible changes
If substitute ols_ for ols everything works
