RPLV (Define a match string from an internal value)

This command allows you to define a match string based on the setting of an internal plotting parameter, or by reading user input. The match string may then be used in the following commands.

Command Syntax:

RPLV match,parm,fmt,prompt

Command Parameters:

match	The match string to be set. This string may be any unique string, but we recommend that it be framed be dots in order to be compatible with command-line replacement strings.
parm	A four letter parameter mnemonic:
	ATTR	Attribute name stripped from an attribute defined by text. This allows you to extract an attribute name from an attribute defined previously
	DCNT	0 if not the end of the input data file
		1 if at the end of the input data file
	DEOF	0 if the whole line was read into the buffer
		1 if the last line was truncated
	DMNX,DMNY,DMNZ	Minimum X,Y or Z (respectively) value in the buffer
	DMXX,DMXY,DMXZ	Maximum X,Y or Z (respectively) value in the buffer
	DNPT	Number of points in data buffer (integer)
	DSCX,DSCY	X or Y scale in ground units/map unit
	DLNM	Data buffer line number (integer)
	DLTP	Data buffer line type (Line", "Base Line", "Tie Line", "Test Line", "Trend Line" or "No Data" if the buffer is empty)
	PPCS	Projection name
	PDAT	Projection datum name
	PLDT	Projection local datum stransform name
	PMTH	Projection method name
	PUAB	Projection unit abbreviation
	PUNI	Projection unit full name
	PELL	Projection ellipsoid name
	WDNX,WDNY,WDXX,WDXY	Data window minimum and maximum (respectively) coordinate values.
	WGNX,WGNY,WGMX,WGMY	World minimum and maximum (respectively) coordinate values.
	WMNX.WMNY,WMMX,WMMY	Map minimum and maximum (respectively) coordinate values.
fmt	A FORTRAN style format with the following syntax:
	"(Fw.d)"	Floating point format, where w is the string width, and d is the number of digits after the decimal.
	"(Iw)"	Integer format, where w is the width of the field in which the integer is placed right justified. If w is 0, the number is left justified. The default is "(I0)"
prompt	A text string used by the ATTR and USER parameters.

group.parm value from the Advanced Settings file i.e. "MAPPLOT.FEET"

Example

PAGE 1,1,10.5 /define a plot area

RECT 1 /draw a box around plot area

DATT .a. /define attribute .a.

RPLV .a.,ATTR,,.a. /reduce .a. to its name only

RECT 1,2,2,3,3,.a. /plot box legend using .a.

TEXT 1,3.5,3.3,-1,".a." /box legend label

:kt150,0.3 /text attribute override

This command is part of the MAPPLOT GX.
