If the communications software does not allow you to specify file characteristics, try the following approach for z/OS:

PROC CPORT and PROC CIMPORT can lose precision on numeric values that are extremely small and large. Refer to Loss of Numeric Precision and Magnitude in SAS/CONNECT User's Guide for details.
