How to split a tab delimited file from application server in 4.6C

Hi,

How to split a data in tab delimited text file from application server in 4.6c version.I have done same thing in version ECC6 using SPLIT l_string

AT cl_abap_char_utilities=>horizontal_tab "Horizontal tab

INTO l_funcloc_clas-tplnr

w_funcloc_clas-class

w_funcloc_clas-klart

w_funcloc_clas-atnam

w_funcloc_clas-atwrt

w_funcloc_clas-atfor.

But this class( cl_abap_char_utilities) is not available in 4.6C version.
