CODECIML: Converts between decimal and sexagesimal coordinates

INPUTS

          Input adverbs
DECIMAL          -1.0          1.0 > 0 -> decimal > sexagesimal
         $Input/output adverbs
COORDINA $                         Sexagesimal coordinate
X        $                         Right ascension in degrees
Y        $                         Declination in degrees

HELP SECTION

CODECIML
Type:  verb
Use:   To convert between sexagesimal and decimal coordinates.
Input adverbs:
  DECIMAL....> 0 => go from decimal (X, Y) to sexagesimal (COORDINA)
Input/output adverbs
  COORDINA...The X and Y coordinates are found as:
             Xpos = abs(CO(1)) + abs(CO(2))/60 + abs(CO(3))/3600
                if any of CO(1), CO(2), CO(3) < 0: Xpos = -Xpos
             Ypos = abs(CO(4)) + abs(CO(5))/60 + abs(CO(6))/3600
                if any of CO(4), CO(5), CO(6) < 0: Ypos = -Ypos
             Note that, although these are most suited to RA, Dec in
             sexagesimal notation, they can be used for any type of
             coordinate.  The units are standard FITS units (e.g
             degrees, m/sec, Hz, sec, etc.) except that right
             ascensions are in hours of time.
  X..........Right ascension in degrees
  Y..........Declination in degrees
