// Created: MBN 04/04/89 -- Initial design and implementation
// Updated: DKM 07/07/89 -- To work around Xenix 31 char limit:
// Shortened is_less_than to is_lt
// is_greater_than to is_gt
// is_less_or_equal to is_le
// is_greater_or_equal to is_ge
// Updated: MBN 12/15/89 -- Made case-flag optional on is_equal, is_not_equal
// Updated: DLS 03/22/91 -- New lite version
// Updated: JAM 08/11/92 -- removed DOS specifics, stdized #includes
// Updated: JAM 08/11/92 -- removed "fast" TOLOWER/UPPER; just use ANSI C's
//
// This header file defines function prototypes for extended char*
// functionality patterned after that of the CoolString class. This will allow a
// programmer to chose char* or CoolString strings for an application based upon
// the needs of the program and not the availability of a particular function
// or functions. Note that there is no attempt to allocate or deallocate
// memory. Functions for comparison (both case sensitive and insensitive),
// case conversion and string token trimming are provided. All functions
// assume pointer operands are passed.
