Hi, Palmer:
I neither own nor know in depth this model, but it seems to me that it's unlikely to have indirect addressing for the following reasons:
- First, I've been unable to find any reference to indirect capabilities in this machine despite lots of searching.
- Second, a glance at its keyboard doesn't seem to reveal any legend on the keys that could correspond to an index register, indirect addressing, etc.
- Third, with just 128 steps of program memory and only 12 memory registers, all of them likely to be directly addressable being that few, I don't see any real use for indirect addressing in this machine.
In any case, if I were your correspondent, I would kindly ask Mr. Toth himself, as he seems to own one and be very knowledgeable about it.
There's also a firm on the web which claims to provide nearly every manual under the sun, in PDF format, for a fee, and this model appears in their list of available ones. Google for "manuals in PDF" if willing to give it a try.
Best regards from V.

The Sharp PC 1201 belongs to a class for handheld (aka pocket) computers that use the old line-numbered BASIC. You create arrays using the DIM statements and then you access the array elements using other variables whose values represent indices for the array ... that's how indirect addressing works in BASIC pocket computers.
