I ran into an overflow problem when I used Stat Transfer to convert an
Excel file of Compustat variables to a Stata dataset. The problem
turned out to be the CUSIP variable (a firm identifier variable that has
numbers and letters), which I failed to format as a string variable.
Because of the letter E in some CUSIPs, some "values" were read as
exponential numbers. Once I corrected that problem, the overflow
problem was also corrected.
