The Edit Data Area 2  command allows you to key over  the existing data
in  a  character data  area.   The  edit  display appears  in  the same
format  as used  by DSPDTAARA.   Each  line of  50 bytes is  a separate
field.

Thus you can key (or  key over) formatted lines with EDTDTAARA2.   This
allows for the values to be easily seen with DSPDTAARA.

The  EDTDTAARA  tool  also   allows  editing,  but  treats  the  entire
contents as a single field on the display.

The EDTDTAARA3 allows editing in Hex.

A typical command would be:

           EDTDTAARA2   DTAARA(xxxx)

When  the display appears, 9  lines (450 bytes) are  displayed.  If the
data area size is greater than  450 bytes, rollup is allowed to  access
each  succeeding 450  bytes.   Rolldown  is valid  to re-display  prior
screens.

When the  user presses Enter, a  check is made to  ensure that data has
not been keyed beyond  the actual length  of the data  area.  An  error
message will be displayed if this occurs.

If data  below  X'40' exists,  it is  changed  to blank  and and  error
message will appear.

Contrast with other functions
-----------------------------

The  system  CHGDTAARA command  does  not  allow you  to  key over  the
existing  value.  You  can change the  data, but the  existing value is
not displayed.

The TAA  Tool command  EDTDTAARA allows you  to key  over the  existing
value, but  considers the entire  data area as  a single field  (if the
data  area is less  than 800 bytes  in length).  EDTDTAARA  can be used
to edit decimal data areas.

Depending  on what  use  you  are  making  of  the  data  area,  either
EDTDTAARA or EDTDTAARA2 should meet your editing needs.

Command parameters                                    *CMD
------------------

   DTAARA        The  qualified  file  name  of the  data  area.    The
                 library  value  defaults to  *LIBL.    *CURLIB may  be
                 specified.

Restrictions
------------

Only character data areas may be  edited.  For numeric data areas,  use
EDTDTAARA.

If characters below  X'40' exist, a  prompt for the  EDTDTAARA3 command
occurs.

If the  TAALICENSE data area in TAATOOL,  TAAINS, TAAINS2, or TAAINSLIC
is specified, no changes can occur to positions 1901 - 2000.
