pass in parameters

Former Member — Wed, 19 Jul 2006 14:43:22 GMT

Hello, I have the following line in one of my forms:


 FORM PRINT_THINGS TABLES P_COL_WIDTH
                     USING P_DATA_DETAIL(1000) TYPE C.

where p_col_width is the width of each column of a table (i.e., p_col_width is an internal table) and p_data_detail is a string containing all the actual data. When I tried to run it, however, this is what I got:

Parameters must be specified either with "p" (pass by reference) or with "VALUE(p)" (pass by value).

May I know what is wrong with this code? Thanks a lot!

Regards,

Anyi

You can directly define the length and type in the FORM statement, you must use a TYPE, or LIKE.
