I think -outdat- downloadable from SSC comes near to what you want. The aim of 
-outdat- is to write a dataset to an ASCII File and to write dictionaries for 
various statistical packages (i.e. Limdep, SQL, Rats, RUMM, Stata, SPSS) to 
read and label that ASCII-File. Before saving the ASCII-File, outdat sets a 
fixed display-format for each variable according to the storage type. If you 
take care of the storage type (-compress-), and -outdat- afterwards, you 
should get what you want.

To install type

. ssc install outdat

Many regards
