In Stata 8, you can type
. saveold filename7
The -saveold- command will save your dataset so that it can be read by Stata 7.
However, Stata 6 will still not be able to read this. But, if you have access
to Stata 7, you could then open the dataset you just created with Stata 7 and
. save filename6, old
This would convert the data from Stata 7 format to Stata 6 format. The
-saveold- command replaced this command in Stata 8. Going through this
two-step process would convert the data so that Stata 6 could read it.
The only other alternative I can think of would be to use the -outfile- or
-outsheet- command to create an ASCII text file of the data. You could then
use -infile-, -infix-, or -insheet- to read the data into Stata 6.
In doing this, you might run into limit issues, such as length of variable
names (Stata 6 had a limit of 8 characters and Stata 7 and 8 have limits of 32
characters), maximum number of variables, string lengths (Intercooled Stata 6
limited strings to 80 characters and Stata 7 SE and 8 SE limit them to 244
In the end, the best solution might be to encourage your friends to upgrade to
