RE: st: RE: Variable name length limit

For a start, you need to state the source of this program.
I doubt there is any Stata command that does this, only user-written commands.

It looks like the program is making some temporary variables and it's doing it by adding stuff to your existing variable name.  It should be using -tempvar-.

You can't change the variable name length limit: it's a limit.

So either:
1) make you variable names shorter; or
2) edit the -diff- program and make it work properly.

Yes it is a user-written command, but widely used nowadays.

This is just an example. There are standard Stata commands that do
this too. My point was how I can disable the 32-character limit on
variable name.

Thanks,
James

If it is a user-written command, then the person who wrote it is responsible for the behaviour of the command. You can either wait for that person to reply, or modify their ado file to fix the problem yourself, or perhaps the easiest way is to just shorten your variable name.
