Is there a portable ADS with an ISAM interface?

Hi,

You need to be sure that the result of the index key is always the same lenght.

INDEX ON SUBSTR(FIELDGET(ff),1,256) TO Inp_tmp UNIQUE

If the result if fieldget(ff) is less than 256, the indexkey won't be 256 characters!

INDEX ON PADR(FIELDGET(ff),256," ") TO Inp_tmp UNIQUE
With PADR it will always be the same lenght.

Secondly, I don't know if an indexkey can be 256 characters in lenght. I don't think it can.

Thank you very much, Skiman! Now everything has worked out. I will keep this requirement in mind
