DS D defines a floating point field. 4110000000000000 is a normalize floating point 1. Use FD for a fixed 64-bit integer. LTORG is irrelevant. Works the same as a literal or as a DC.

Somewhere between 95-2002 IBM added the type-extension subfield to the DC instruction. As of 2004, D became a valid type-extension, which clarifies characteristics of the type, so in type-extension context, D is doubleword.
