Hi Jeff,

I can also not remeber all. Still after 10 years practice, the Philips IC20 book has its place on my table.

Also your question can not be answered short, since it depends...
- you can use 8 register variables
- you can use 32 register variables (8 per 4 banks)
- you can use 128 bits as bit variables
- you can use 128 byte variables (DATA)
- you can use 256 byte variables (IDATA)
- you can use 65536+256 byte variables (+XDATA)
- you can use MBytes (paging XDATA)
