WebDescription. If the common block name is omitted, then blank common block is assumed. Any common block name including blank common can appear more than once in COMMON statements in the same program unit. The list nlist following each successive appearance of the same common block name is treated as a continuation of the list for … WebXL Fortran for AIX 8.1 Language Reference CSHIFT(ARRAY, SHIFT, DIM) Shifts the elements of all vectors along a given dimension of an array. The shift is circular; that is, elements shifted off one end are inserted again at the other end. ARRAY is an array of any type. SHIFT must be a scalar integer if ARRAY has a rank of one; otherwise, it is
