The effect of SECTALGN depends on the level of program object compatibility requested in the binder COMPAT option. By default, alignment stronger than quadword is rounded up to 4K, for compatibility with the limitations of the load module format. I think a COMPAT value of ZOSV2R1 or above is needed for the binder to fully respect SECTALGN alignments.
