Now able to run GLM, I have searched extensively but unsuccessfully for assurance that when all data are normalized GLM runs floating point in double or extended precision. I have not been able to find a clear statement that it does or a way to tell it to do so.
Help would be greatly appreciated.

The document that Reeza linked to is "truly definitive." All SAS procedures do floating-point computations in double precision, which is the standard in the world of numerical analysis.

If you don't like the default output then use the NOPRINT option and direct output to datasets such as OUTSTAT= option for the proc statement or an OUTPUT statement. Then you can use any of the report procedures such as Print, Report or Tabulate to display the values and specify the format(s) desired.
