Thanks Jonathan,

I'll ask our support department to install this APAR.

Fred!

This is a bug which was fixed by HLASM APAR PH08424 in Feb 2019.

The problem was only likely to occur after the TRUNC support fixes in APAR 
PH06572.  The existing code for handling zero-length values was in error in 
bypassing the logic to initialise the constant value to spaces (and also in 
bypassing the logic to translate those spaces to ASCII for an ASCII
constant) but before the TRUNC changes the value area was likely to contain 
blanks anyway by chance.
