Proc Getdata
============

The following is an alphabetical list of the Getdata parameters.
Given are: the parameter name; the parameter data type; a default
value if any; and a description.  Especially important parameters
have a "**" in the right margin.

-------------------------------------------------------------------
Append:		{y,n}				: n		
  Allows new data will be put "below" existing data.
-------------------------------------------------------------------
Datafile:	token (M)  			: 		**	
  Data file name
-------------------------------------------------------------------
Data:		text				:		**
  The following lines contain data.
-------------------------------------------------------------------
Join:		{y,n}				: n		
  Allows new data to be put "beside" existing data.
-------------------------------------------------------------------
Percents:	dfield (list20)			:		
  Convert the specified fields from N to percentages of column 
  total.
-------------------------------------------------------------------
Selectfields:	token (list20)			: all		
  Select only these fields from input.
-------------------------------------------------------------------
Startline:	number				: 1		
  This allows only a portion of the rows of data in a file to be
  read into IPL.  This specifies the line to start with (first line 
  is line 1).  See also Stopline.
-------------------------------------------------------------------
Stopline:	number  			: 9999		
  Stop reading after this line is read.  (See Startline)

#
# This Proc must be used before doing any plotting.  Data can be
# read from a file (Datafile) or contained within the Data 
# parameter.  A few data manipulation functions are included,
# but the intent is for most of this kind of thing to be done
# using Unix utilites.
#
# BUGS: It would be nice to be able to do percents based on the
#   row total.
