Obsolete Syntax
SEARCH dobj FOR pattern [IN {CHARACTER|BYTE} MODE]
[STARTING AT p1] [ENDING AT p2]
[ABBREVIATED]
[AND MARK].
Extras
1. ... IN {CHARACTER|BYTE} MODE
2. ... [STARTING AT p1] [ENDING AT p2]
3. ... ABBREVIATED
4. ... AND MARK
Effect
This statement searches the data object dobj
according to the search pattern
specified in pattern
. The additions allow you to search subareas, shortened patterns and marking of places of finding.
The search ends at the first hit and sy-fdpos
is set to the offset of the
found pattern or to the word in the search area. If the pattern is not found, then sy-fdpos
is set to value 0.
Search Pattern in pattern
The pattern in pattern
can have the following forms (upper or lower case is irrelevant in character chain processing):
-
"pat"
In character chain processing, blanks at the end of the character chain are ignored and wildcard characters (*) are treated in a special way if they are found at the position of the first or last character (see following sections). -
".pat."
Only valid for character chain processing. If a pattern "pat" is enclosed by periods (.) , then exactly the character sequence "pat" is searched for, whereby blanks at the end are accounted for and wildcard characters (*) are not treated as wildcards. -
"*pat"
Only valid for character chain processing. If a pattern contains the wildcard character (*) as first character, then a word is searched for (see below) which ends with the character sequence "pat". -
"pat*"
Only valid for character chain processing. If a character sequence contains the wildcard character (*) as its last character, a word (see below) is searched for that begins with the character sequence "pat". -
"*pat*"
Only valid for character chain processing. If a character sequence contains the wildcard character (*) as both first and last character, then the search is not for a word (see below) that contains "pat", but a word that ends with "pat*".
A word in a character-like data object dobj
is defined: Enclosed by non-alphanumerical separators.
During string processing with data objects dobj
of fixed length, the closing
empty character is taken into account, while with pattern
it is not. If
pattern is an empty string or is of type c
, d
,
n
or t
and only contains empty characters, the search is never successful.

Notes
-
We recommend that you use the new statement
FIND
instead ofSEARCH
, wherever possible. The functions ofSEARCH
have - with the exception of marking the found pattern (additionAND MARK
) - been covered by the introduction of regular expressions into the statementFIND
. If required, marking after a pattern has been found can be replaced by the statementREPLACE
or the built-in functionreplace
. Here, the replacement patterns for regular expressions are particularly useful. In contrast toFIND
,SEARCH
cannot distinguish between upper and lower case, and is must slower when searching large texts. -
A variant of this statement used for searching tables -
SEARCH itab - has also been replaced by a variant of statement
FIND
.
Addition 1
... IN {CHARACTER|BYTE} MODE
Effect
The optional IN {CHARACTER|BYTE} MODE
addition determines whether
character string or byte string processing
is carried out. If the addition is not specified, character string processing is carried out. Depending
on the processing type, dobj
and pattern
must be either character-like or byte-type.
Addition 2
... [STARTING AT p1] [ENDING AT p2]
Effect
With the additions STARTING AT
and ENDING AT
,
you can restrict the search to a subarea of the data object dobj
. For
p1 and p2
, data objects of the data objects of the data type i
are expected.
The value in p1
specifies the first, the value in p2
specifies the last of the positions to be searched. Without specifiying STARTING
AT p1, the data object dobj
is searched from the first position to
position p2
. Without specifying ENDING AT p2
, dobj
is searched from position p1
to the end.
If the addition STARTING AT
is specified, then sy-fdpos
is set to the offset of the find location minus the offset of p1
, provided
that the search was successful. In the following cases, the search is not carried out, and sy-subrc
is set to 4:
-
The value of
p1
orp2
is less than 1. -
The value of
p1
is greater than the length ofdobj
. -
The value of
p2
is less than or equal top1
.
Note
The term "position" is not equivalent to the term "offset". A byte or a character on position 1 has an offset of 0.
Addition 3
... ABBREVIATED
Effect
With the addition ABBREVIATED
, you can specify a shortened pattern in
pattern. This addition is only possible with character chain processing. A word is searched in
dobj
that begins with the same character as the pattern in pattern
and contains the remaining characters of "pattern" in the same sequence, but at otherwise completely arbitrary positions of the word.
Example
Search for an abbreviated pattern with SEARCH
. The FIND
statement has the same result and also specifies the find location.
DATA: text TYPE string VALUE `Roll over Beethoven`,
moff TYPE i,
mlen TYPE i.
SEARCH text FOR 'bth' ABBREVIATED.
FIND REGEX '\<(b[a-z0-9]*t[a-z0-9]*h[a-z0-9]*)\>' IN text
IGNORING CASE
MATCH OFFSET moff
MATCH LENGTH mlen.
Addition 4
... AND MARK
Effect
With the addition AND MARK
, a character sequence found in dobj
or a found word, is converted to upper case. This addition is only possible with character chain processing,
and you are only allowed to specify changeable data objects for dobj
when you use it.
Example
The first two SEARCH
-statements have the same effect. They find the first
blank in text
and set sy-fdpos
to the value 4.
The third SEARCH
statement finds the word "Beethoven" in the search area
(beginning from position 6 of text
), sets sy-fdpos
to the value 5. In other words, the offset of the place of finding in the search area and changes the content of text
to "Roll over BEETHOVEN".
DATA: text TYPE string VALUE `Roll over Beethoven`,
pos TYPE i.
SEARCH text FOR '. .'.
SEARCH text FOR ` `.
IF sy-subrc = 0.
pos = sy-fdpos + 2.
SEARCH text FOR 'bth' STARTING AT pos
ABBREVIATED AND MARK.
ENDIF.
