MSC

 Projection     : Modified Stereographic Conformal
 Also known as  : Alaska Grid
 General class  : modified azimuthal
 Characteristics: conformal
 Earth model    : only Clarke 1866 (NAD 1927)

Defining the MAPUNITS:

 MapUnits "msc"  ! Standard name

Other parameters:

 FalseEasting  "false_easting"   ! Optional, default is zero
 FalseNorthing "false_northing"  ! Optional, default is zero

Possible errors:

 E330, "Calculation failed to converge to a solution" - In converting 
        from projection coordinates to geographic coordinates, too 
        many iterations were made.
