  Generally used in a continue block at the end of a loop to clearvariables and reset ?? searches so that they work again. Theexpression is interpreted as a list of single characters (hyphensallowed for ranges). All variables and arrays beginning with one ofthose letters are reset to their pristine state. If the expression isomitted, one-match searches (?pattern?) are reset to match again. Only resets variables or searches in the current package. Always returns1. Examples:

   reset 'X';  # reset all X variables
   
   reset 'a-z'; # reset lower case variables
   
   reset;  # just reset ?one-time? searches
