IBRAV and six lattice constants CELLDM(I)(I=1,6) are specified in this order to the 1st line. A blank character is kept from entering before IBRAV. Each parameter is divided with the blank of one character.

IBRAVと6個の格子定数CELLDM(I)(I=1,6)を、この順に1行目に 指定する。IBRAVの前には空白文字が入らないようにする。 各パラメーターは、空白1文字で区切るようにする。
