C_STR

 The C_STR function takes a compile-time  string  expression  and
 returns  a  C_STR_T  pointer  to  a static string literal with a
 terminating null character.


 Syntax:

    C_STR(e)


 The C_STR function can also accept a Pascal variable  of  either
 PACKED ARRAY OF CHAR, VARYING OF CHAR, or STRING.


 Syntax:

    C_STR(v)


 In this form, it will return a C_STR_T value that represents the
 first  character  in  the string variable.  It does not ensure a
 terminating  null  byte.   The  programmer   must   handle   the
 null-termination   to  treat  a  Pascal  string  variable  as  a
 null-terminated string.
