How do I format HSERIN?

[skimask]

Thanks for that Bob. The bit I was confused about is Skimask's statement "MyVars var Byte[8] sets aside 9 bytes, index 0 (zero) is also valid"
I thought I understood that MyVars VAR BYTE[8] had 8 elements numbered 0 to 7 (Page 26 PBP new manual). If that were the case then the 'clearance' counter ought surely to be 0 to 7 not 0 to 8, which would be invalid.

Ya know...you're right. I've been reading that line in the manual 'bass-ackward' all this time. Never had a problem with it, but still.........
