For this to work, the length modifier has to be not only "defined" in the sense that it has been seen, but resolved, so that the numeric value is known at the time it is used. If the length of TKJSONPF was not known when the EQU was encountered, resolution is deferred, which means that the definition has not yet taken effect. There are other similar errors where something is documented as needing to be predefined, but it also needs to be resolved. I've already made a note that we should try to clarify this in the message explanations. Jonathan Scott, HLASM IBM Hursley, UK
