As the version of Stata you are using won't allow
string variables longer than 80 characters, you
will need to use a version of Stata which does,
or fix this outside Stata.
I don't think there is another Stata solution, except
possibly by writing a program using -file-.
Some other possibilities are
* doing something in whatever generated this to split
or shorten your variables
* fixing this with Stat-Transfer or DBMS/Copy
* writing a script in Perl, Python or some other
scripting language
* fixing the problem in a text editor.
For what it's worth, I have written a package -intext-, downloadable from
SSC, which reads text files into a Stata data set with as many string
variables as necessary to represent the longest record. The user can then
process these variables further. In Stata, you can find out more about this
package by typing type
