The aim of this note is to study the IP-complemented subspaces in ORLICZ function spaces LV(0, co) over the infinite interval (0, co). Several results previously given by the authors in ([H-R,]) for the ORLICZ spaces 1, and Lq[O, 11 are extended to the class of ORLICZ function spaces Lv(O, 00). The structure of the ORLICZ function spaces L"(0, co) has been studied by N. J. NIELSEN ([N]) and also by W. JOHNSON, B. MAUREY, G. SCHECHTMANN and L. TZAFRIRI in ([J-M-S-TI). Several interesting results on the 1 P-embedding into the ORLICZ spaces l+' and LV[O, 11, given by J. LINDENSTRAUSS and L. TZAFRIRI ([L-TI], [L-T,]), were extended to the case of spaces Lq(0, co) by NIELSEN in [N], where (also somewhat) unexpected peculiar properties of the spaces LV(O, co) are showed, which are specific for this class of function spaces over the infinite interval (0, a). For example, in Theorems 1.5 and 1.6 of [Nl, it is proved that the set of p's for which the unit vector basis of l P is
