LOGICAL FUNCTION PRSEDT (BUFFER,BEGBUF,ENDBUF)
C$ (Parse Internal - Edit)
C$ Handle inline editing functions in text stored as ASCII
C$ ordinals in BUFFER(*) from BUFFER(BEGBUF) ..
C$ BUFFER(ENDBUF). The editing functions are implemented by
C$ replacing characters in BUFFER(*) by DELCHR, the deleted
C$ character flag. If the editing produces changes in the
C$ line which require that it be retyped, the function value
C$ returned is .TRUE.. Otherwise, it is .FALSE.. On return,
C$ ENDBUF is reduced if necessary to guarantee that
C$ BUFFER(ENDBUF) does not contain DELCHR, thereby freeing
C$ buffer space. An empty buffer is signalled by ENDBUF .LT.
C$ BEGBUF. The caller can determine whether a reparse is
C$ necessary by comparing ENDBUF with the index of the last
C$ character of the most recent successfully-parsed field.
