(*
   StrConCat - combines a and b into c.
*)

StrConCat
PROCEDURE StrConCat (a, b: ARRAY OF CHAR; VAR c: ARRAY OF CHAR) ;

(*
   StrLess - returns TRUE if string, a, alphabetically occurs before
             string, b.
*)

StrLess
PROCEDURE StrLess (a, b: ARRAY OF CHAR) : BOOLEAN ;

(*
   StrEqual - performs a = b on two strings.
*)

StrEqual
PROCEDURE StrEqual (a, b: ARRAY OF CHAR) : BOOLEAN ;

(*
   StrLen - returns the length of string, a.
*)

StrLen
PROCEDURE StrLen (a: ARRAY OF CHAR) : CARDINAL ;

(*
   StrCopy - copy string src into string dest providing dest is large enough.
             If dest is smaller than a then src then the string is truncated when
             dest is full.  Add a nul character if there is room in dest.
*)

StrCopy
PROCEDURE StrCopy (src: ARRAY OF CHAR ; VAR dest: ARRAY OF CHAR) ;

(*
   IsSubString - returns true if b is a subcomponent of a.
*)

IsSubString
PROCEDURE IsSubString (a, b: ARRAY OF CHAR) : BOOLEAN ;

(*
   StrRemoveWhitePrefix - copies string, into string, b, excluding any white
                          space infront of a.
*)

StrRemoveWhitePrefix
PROCEDURE StrRemoveWhitePrefix (a: ARRAY OF CHAR; VAR b: ARRAY OF CHAR) ;
