st: New version of -chardef- on SSC

["Roger B. Newson" <r.newson@imperial.ac.uk>]

Thanks as always to Kit Baum, a new version of the -chardef- package is 
now available for download from SSC. In Stata, use the -ssc- command to 
do this, or -adoupdate- if you already have an old version of -chardef-.

The -adoupdate- package is described as below on my website, and sets 
characteristics for a list of items. In the new version, -chardef- and 
-charundef- input an extended varlist (or evarlist), which is a list of 
items which may be variable names or the name -_dta-, implying that we 
are setting or unsetting characteristics of the dataset currently in 
memory. For example, the user may type

charundef _dta

and clear all characteristics of the dataset currently in memory. Or the 
user may type

charundef _dta *

and clear all characteristics of the current dataset and of all 
variables in the current dataset.

Best wishes

Roger

TITLE
      chardef: Assign values to a characteristic of a list of items

DESCRIPTION/AUTHOR(S)
      chardef is a mass-production version of the char define
      command.  It assigns a list of values to a named
      characteristic of a list of items, which can be variables, or
      the current dataset.  If the evarlist is not supplied, then
      chardef assigns the values to the named characteristic for
      all variables in the dataset currently in the memory.  If the
      named characteristic is not supplied, then the values are
      assigned to the characteristic varname, used by the list
      command.  If the list of values is shorter than the evarlist,
      then the list of values is extended on the right with copies
      of the last value.  Optionally, a prefix and/or a suffix may
      be added to the values.  The charundef module resets a list
      of characteristics to empty strings for a list of items.
