passing variable to macros

[Former Member]

hi

i have a problem for passing the variable to macros

in the following code i have to pass the variable sy-index to the variable p_old&1,p_new&1 so that they become p_old1,p_old2,p_old3----p_old14 as the loop progresses. but it is throwing syntax error saying that p_oldsy-index is not defined

please help in this

DEFINE ADD_MAPPING.

TB_VALUE-OLD = P_OLD&1.

TB_VALUE-NEW = P_NEW&1.

APPEND TB_VALUE.

END-OF-DEFINITION.

DO 14 TIMES.

ADD_MAPPING 1." WRONG HERE

ENDDO.

Vijay,

For macros you pass values not variable names. The value does not get concatenate and become P_OLD1, the way you are doing.

You will have to take care of the sy-index at the place where you are calling the macro.

Hi vijay,

1. it should be like this (partly)

2.

report abc.

data : begin of tb_value occurs 0,

old(10) type c,

end of tb_value.

DEFINE ADD_MAPPING.

TB_VALUE-OLD = &1.

*TB_VALUE-NEW = P_NEW&1.

*APPEND TB_VALUE.

END-OF-DEFINITION.

DO 14 TIMES.

ADD_MAPPING 1." WRONG HERE

ENDDO.

Hi Vijay,

Try this code...

DATA p_old1 TYPE i VALUE 10.
DATA p_c(10).
FIELD-SYMBOLS: <fs> TYPE ANY.

DEFINE ADD_MAPPING.
p_c = &1.
CONDENSE p_c.
CONCATENATE 'p_old' p_c INTO p_c.
ASSIGN (p_c) TO <fs>.
TB_VALUE-OLD = <fs>.

p_c = &2.
CONDENSE p_c.
CONCATENATE 'p_new' p_c INTO p_c.
ASSIGN (p_c) TO <fs>.
TB_VALUE-NEW = <fs>.

APPEND TB_VALUE.

END-OF-DEFINITION.

DO 14 TIMES.
ADD_MAPPING sy-index.
ENDDO.
