As I said bafore, Mr. Jensen's code fragment will not always work. It will not work if your installation specifies the SWA above the line. This code fragment will always work. Your code specifies AMODE 31, though if it works it will work with AMODE 24. The SWAREQ macro requires AMODE 31.

The Load instruction after the SWAREQ macro call will load the correct address of the JCT. |
