Background:  Here are the steps to Generate Points that may come from a GPS into ArcINFO.
to generate a point file using ARCINFO

NOTE:  If using GIS LEVEL GPS equipment, be sure to set precision to double double 
before the Generate Session.  WHY?  When converted to Decimal Degree any AI with Fuzzy
or Tolerance set to less than 1 meter, will not be recognized in the decimal equivalent
of decimal degrees.

STEPS:

You have obtained points using GPS and want to generate a point file.

Use a text editor such as notepad to create a file using the style below:\

1,-149.6216394,60.18781181
2,-149.6226272,60.18696522
3,-149.6218753,60.18675015
4,-149.6207358,60.1868129
5,-149.6221496,60.18621418
6,-149.625052,60.18631777
END

Save the file as an ASCII comma delimeted file.

In ARC/INFO:
precision double double (see NOTE above)

generate <pointcov>
input <name of file>
points
quit
