Figure 1 shows the sequence of events that might occur following the issuance of this macroinstruction. Here is an example of a SEND macroinstruction that specifies

Figure 2 shows the sequence of events that might occur following the issuance of this macroinstruction. Figure 1. General sequence of events when ECB-posting
is specified
Figure 2. General sequence of events when an
