Default Re: Karens PAGE2.SYS relocated to PAGE3 for NIBL-E systems

Its ok its me, MOD in FP is a different format to NIBL:
Code:
NIBL:       PRINT MOD(x,y)
NIBLFP:     PRINT x MOD y
another significant change is indirection:

Code:
NIBL:       @(x)=y : z=@(x)
NIBLFP:     POKE x,y : z=PEEK(x)
I think the reason for the slow loading via the console is cos unlike NIBL which simply stores a program as ASCII text,
FP is tokenised and every line is processed as its loaded, so theres a delay before the prompt reappears - hundreds of ms.
I think a straight binary load of the tokenised page is the way to go - 2400 no delays

So that would explain why a program that exceeds the page memory in NIBL generates an AREA ERROR (i.e. out of memory) but NIBL-FP is able to accommodate it. (I thought at first that NIBL-FP is loading across multiple pages)
