Former Member — Sat, 07 Apr 2007 08:28:51 GMT

hi all,

When i m executing this code an error " p & c are type incompatible" is coming.

Please advise.

REPORT ztx1013.

PARAMETERS p(20) DEFAULT 'c::
\xxx
yyy'.

DATA: c, "current character

n. "next character

DO 19 TIMES VARYING c FROM p0 NEXT p1

VARYING n FROM p1 NEXT p2.

IF c NA ':\'.

CONTINUE.

ENDIF.

IF c = n.

WRITE: / 'duplicate', c, 'found', 'at position', sy-index.

ENDIF.

ENDDO.

Try

REPORT ztx1013.
PARAMETERS p(20) DEFAULT 'c::\xxx\yyy'.
DATA: c, "current character
n. "next character

DO 19 TIMES VARYING c FROM p+0(1) NEXT p+1(1)
VARYING n FROM p+1(1) NEXT p+2(1).
IF c NA ':'.
CONTINUE.
ENDIF.
IF c = n.
WRITE: / 'duplicate', c, 'found', 'at position', sy-index.
ENDIF.
ENDDO.

Regards

I fear you have to remove the varying and replace them with

pos = sy-index - 1.
c = p+pos(1).
n = p+sy-index(1).

(less elegant)

I always used varying with subfields of a structure not with characters of a field. Abap documentation points on fields :

<i>This addition is useful if you have a series of fields of the same type and the same distance from each other.</i>
