set_var_col_const

PURPOSE

SYNOPSIS

DESCRIPTION

 Assigns an index to a field that is named after given variable

 col = set_var_col_const(var_list);

 This is a generic mechanism for assigning an index to a field that is named
 after a variable in the variable list. This allows for scripts to index into
 data using names and saves the script author from having to do strmatch()
 lookups each time.

 See also: set_form_col_const.m for a fixed set of column IDs
