41CL — PowerCL_Ext PWRX XQ1/XQ2 key assignments

On my 41CL (latest available module version), both those keys get me XQ$1.

Am I mis-reading it, or is that how it's supposed to be?

But, I suppose, as they effectively do the same thing, perhaps there's no need? I'm not quite clear on what the difference is between them, at least when not in PGRM.

Thanks for the bug report - you're correct, pressing ALPHA after sCL should call XEQ2. I have corrected this and the new ROM is available - see attached.

W.r.t. the differences between them, your impression is right - very darn similar but they're both needed, let me clarify.

When you call a sub-function they both access it using the name you type in, regardless of which one of the banks it's located on. Thus they're interchangeable when you either call the function in manual operation or enter it as a program line.

However, the lines entered in a program automatically select either one of them, depending on said bank. Therefore if you typed XQ$1 "CLEM" (or XQ$2 "CLEM" ) it registers the lines { XQ$1 , 5 } but typing XQ$1 "ST-YK" ( or XQ$2 "ST-YK" ) registers the lines { XQ$2, 5 }. Both sub-functions have the index#5, each on its own table.

In summary, both launchers need to exist for this purpose, but you don't have to worry about which table to use when typing a sub-function name, as either one will work. - ok, there's a small difference in how long it takes to find the sub-function, since the search is sequential and it starts at the table you direct by using XQ$1 or XQ$2 - but that's not essential...

Hope this clarifies.
