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. C$ (26-APR-84)
