Not on a 2818 (that is a z114 box if my google-fu is correct). Vector Packed Decimal is much more recent, z14 and up I think. The Vector Packed Decimal instructions were introduced in the 2017 PoOP, edition "-11" (12th edition).
There are Vector instructions available on a z114, just not the packed decimal variety.

The format is MMDDYYCC -- if you can imagine it. ;-) When I coded that string of STCM instructions I was certainly wishing for a better way. ;-) Our hosting provider has us on an IBM 2818. I presume it supports those vector instructions but I don't think they are in my PoPs manual (I'm currently on a back-level, unsupported version of the operating system) for me to figure out how to use them or if they will do what I need.
