1.3.1.0 measures.listcodes

1.3.1 get known reference codes
Description

listcodes will produce the known reference codes for a specified measure type. It will return a record with two entries. The first is a string vector of all normal codes; the second a string vector (maybe empty) with all extra codes (like planets).


Inputs
ms	the measure type for which to list
	allowed:	any
	Default:	record

print "\t----\t listcodes Ex 1 \t----"
# Generate some direction
# Note that an empty or non-specified reference code will produce the
# measure with the default code for that measure type
a=me.direction()
print me.getref(a)
#’J2000’
print me.ismeasure(a)
#True
# Get the known reference codes for direction
print me.listcodes(a)
