WebIf the literal pool does not reside in a DSECT, and includes any items that require quadword alignment, and the SECTALGN value defaults to 8, the assemble of the literal causes the issue of an ASMA500E message.

If the literal is assigned a variable, it may be stored in the stack only if it is not optimized away.
