Please consider a precise and detailed specification next time, like
- tags (or field names) are reflected in the header except for the first header field that is NOT found back in the data records but should be filled with data field 4
- fields are separated by ";"
- data field 3 is the time stamp and should be printed with every change after separation of its field name
- data field 4 needs to lose its field name and trailer and then to be printed as first field per line
- alpha only field name of arbitrary length is leading the fields, numerical field values follow without separator
- fields should be printed according to their position in the header.
etc. etc. etc.

Wildly guessing on what MIGHT BE required, I came up with
Code:
awk -F";" '
BEGIN           {HDStr = "Item_Nu;xw;tr;vyy;ANf;Gk;kl"
                 HDCNT = split (HDStr, HD)
                }

$3 != LAST      {LAST = $3
                 gsub (/[^0-9]|.$/, _, $3)
                 print "Time: " $3
                 print HDStr
                }

                {for (i=5; i<=NF; i++)  {IX = match ($i, /[0-9]/)
                                         RES[substr ($i, 1, IX-1)] = substr ($i, IX)
                                        }
                 gsub (/[^0-9]/, _, $4)
                 printf "%s", $4
                 for (i=2; i<=HDCNT; i++)       {printf ";%s", RES[HD[i]]
                                                }
                 printf "\n"
                 split ("", RES)
                }

form_field_just

FORMS(3)						   BSD Library Functions Manual 						  FORMS(3)

NAME

     field_just, set_field_just -- form library

LIBRARY

     Curses Form Library (libform, -lform)

SYNOPSIS

     #include <form.h>

     int
     field_just(FIELD *field);

     int
     set_field_just(FIELD *field, int justification);

DESCRIPTION

     Field justification is only applied to static fields, a dynamic field will not be justified.  The default justification for a field is
     NO_JUSTIFICATION.	The field_just() will return the current justification value of the given field and the justification may be set by call-
     ing the set_field_just() function.

PARAMETERS

     The following are the valid justifications for a field:

     NO_JUSTIFICATION  No justification is to be applied to the field.	In practice, this is the same as JUSTIFY_LEFT.
     JUSTIFY_RIGHT     The field will be right justified.  That is, the end of each line will be butted up against the right hand side of the
		       field.
     JUSTIFY_LEFT      The field will be left justified.  That is, the start of each line will be butted up against the left hand side of the
		       field.
     JUSTIFY_CENTER    The field will be centre justified, padding will be applied to either end of the line to make the line centred in the
		       field.

RETURN VALUES

     The functions will return one of the following error values:

     E_OK		The function was successful.
     E_CURRENT		The field specified is the currently active one on the form.
     E_BAD_ARGUMENT	A bad argument was passed to the function.

NOTES

     The header <form.h> automatically includes both <curses.h> and <eti.h>.
