CONVERT
[GREG2\]CONVERT A0 D0 [Angle] [/TYPE Ptype] [/UNIT Unit] [/SYSTEM
System] [/VAR Var_X Var_Y]
This command assumes that the X,Y buffers (or the 1-D variables Var_X
and Var_Y if option /VAR is used) contain data in the specified projec-
tion (or in absolute spherical coordinates if Ptype is NONE) in the giv-
en angular unit (Degree Minute Seconds or the default Radian), in the
specified System (GALACTIC or EQUATORIAL, default current system) and
converts them to the current system, as defined by SET SYSTEM, and pro-
jection, as defined by command PROJECTION. Note that the projected coor-
dinates are always natural units (i.e. the equivalent of Radians after
projection). There is no provision for "hidden" parts which are treated
exactly as visible ones.
A0 D0 are Hours and Degrees if the input system is EQUATORIAL, Degrees
otherwise.
CAUTION: when using variables, the Var_X and Var_Y arrays MUST BE RE-
AL*8, and WRITEABLE (see HELP DEFINE).
