DRAW

Draw a line from the current pen position to the specified point

Description:

A straight line is drawn from the current pen position to the specified point.

This command is a synonym for PRIM D.

Usage:

draw x y

Parameters:

X = _REAL (Read and Write)
The X coordinate of the point.

If no value is specified on the command line, the value is prompted for.

Y = _REAL (Read and Write)
The Y coordinate of the point.

If no value is specified on the command line, the value is prompted for.

PROJECTION = _CHAR (Read)
The geometry that is to be used for plotting. This is explained in more detail in the section on projections. Allowed values: "NONE", "TAN", "SIN", "ARC", "GLS", "AITOFF", "MERCATOR" and "STG".This parameter is only relevant when marking points.

This parameter is not specified on the command line. The value of the global parameter PONGO_PROJECTN is used. If PONGO_PROJECTN is not defined, the default value "NONE" is used.

RACENTRE = _CHAR (Read)
The centre of the projection in RA (i.e. the angle must be specified as hh:mm:ss.sss). This parameter is only required for PROJECTION values other than "NONE".

This parameter is not specified on the command line. The value of the global parameter PONGO_RACENTRE is used. If PONGO_RACENTRE is not defined, the default value "0" is used.

DECCENTRE = _CHAR (Read)
The centre of the projection in declination (i.e. the angle must be specified as dd:mm:ss.sss). This parameter is only required for PROJECTION values other than "NONE".

This parameter is not specified on the command line. The value of the global parameter PONGO_DECENTRE is used. If PONGO_DECCENTRE is not defined, the default value "0" is used.
