Getting Back Values from Shift Register from Other Loop (FPGA)

[augustg]

Referring to the picture above, both while loops are inside one while loop (not shown in picture). Problem is im trying to execute the numeric control once only and use the value from the second loop after that. I tried many ways and still have no idea how...could someone help? Thanks in advanced

augustg,

You might try using a case structure to route the numeric control into that shift register only on the first iteration of the outer while loop and in all other cases route the output of the case second loops shift register back into the first. Kind of hard to put into words, but something like this:

The case structure to the right that I added has one additional case "Default". In this case the value from the shift register of the outermost while loop is wired straight through. Hope this helps!
