As long as someone puts in a positive seed 0-1 with six digits it ought to be ok.

Let's play safe here. I just read the comment on the 997-generator in the HP67/97 Standard Pac regarding suitable seeds. It says that seed*1E+7 should not be divisible by 2 or 5. So the 7th digit shoud be 1, 3, 7 or 9. This could be easily implemented:

Code:

LBL "S"
RCL 00
"SEED?"
PROMPT
ABS
FRC
9
*
1
+
E5
*
INT
.7
+
E6
/
STO 00
END

This makes sure the initial seed is > 0,1 and ends with a 7. The subsequent random numbers seem to end with a 1, 3, 7 or 9 as well.
Yes, this might be a good solution so that we can safely use the short and fast 997 algorithm.

If you want to I can do this. At the moment it's just "XEQ R" and "XEQ S". But this can easily be changed with a simple "search and replace".
