passing args to routine

[Former Member]

Hi,

this is my problem: I want to set the length of data in a subroutine according to a parameter passed as argument:

FORM string2table TABLES   table
                  USING    line_length
                  CHANGING string.
  " conversion

  " working area
  DATA table_line(line_length) TYPE c.
  ...
ENDFORM

but I get an error about the declaration of data: I want to use this function for creating table of any length of line. Is impossible to have something like this?

thanks

Hello,

Try in this way it will work.

Field-symbols: <table_line> type ANY

FORM string2table TABLES table

USING line_length

CHANGING string.

" conversion

" working area

• DATA table_line(line_length) TYPE c.

Assign line_length to <table_line>.

Now the field symbol will take the lenght of the line_length.

...

ENDFORM

Hi you can try this

FORM string2table TABLES table TYPE ANY

USING line_length TYPE ANY

CHANGING string TYPE ANY.

" conversion

" working area

DATA table_line(line_length) TYPE c.

...

ENDFORM

thanks ... you put me on the correct way for the answer. This is is how I solved:

FORM string2table TABLES   table
                  USING    line_length
                  CHANGING string.

  " line of the table
  FIELD-SYMBOLS: <table_line> TYPE ANY.
  
  " get type of line
  DATA ref_wa TYPE REF TO data.
  CREATE DATA ref_wa LIKE LINE OF table.
  ASSIGN ref_wa->* TO <table_line>.

...
ENDFORM.
