In ABAP, n(m) means start at position "n" in the string, and go one for length "m". So T023-MATKL0(6) means first six characters of T023-MATKL.

Thanks for ur reply , but still i am not clear . Wat is the use of POSITION and LENGTH in declaring data objects

PARAMETERS NAME(20) type c.

the above stmt makes length 20 for data object NAME.

but

Parameters NAME like t023-matkl+0(6)

does it makes any sence????

wat is the exact use of this could u plz explain.......

It defines a parameter with exactly the same format as the first six character of MATKL. I.e. it's identical to

PARAMETERS name TYPE c LENGTH 6.

Why the original programmer didn't just do the above, you'd have to ask him. Perhaps he wanted to provide a semantic reference to MATKL. I.e. give a future programmer, such as yourself, the idea that the parameter is in someway related to MATNR-MATKL. But that is all. It in fact has NOTHING to do with the parameters statement. It is not part of the parameters statement. It is part of data definition.
