Well,

-summarize- never sees the -tempvar- that you intend to use; instead it sees nothing. If -su- sees nothing, it -summarize-s everything by default, including your -tempvar-...

Dear all,
I have written a program to produce some test statistics. However, the program does not seem able to use the temporary variables that I've generated outside of it. For illustrative purposes consider the following lines, where I define a program to summarize a tempvar (my real problem is more complex and that's why I use a program).

// ===================

cap program drop progtempvar;
program define progtempvar;
   args progvars;
   di "`progvars'";
   su `TV`progvars'';
end;

sysuse auto;
tempvar TVprice; ge `TVprice'= price;
progtempvar price;

// ======================

The program would not recognize the temporary variable. Is there a way to get around this without creating a non-temporary variable?
(that is why  " reg price `TVprice' " work instead?) Thanks in advance,

Mario
