##Critical changes:

ALLOT - Do not return address. Use CREATE <NAME> <num> ALLOT instead of <num> ALLOT CONSTANT <NAME>

ISNUM and ISUNUM takes a string as a parameter.

FIND ( str --> str 0 | addr flag)
Returns str and 0 if the word is not found. Otherwise command address and flag.
flag = -1, if this is a common command.
flag = 1, if the command has a immediate flag.

##Renamed:

[ <--> ]
\ <--> MOD
,C --> C,
,S --> S,
RADIX --> BASE

##Removed:

##Added: ARUN - variable that contains the address of the function that will be executed after the first boot.

R@ - copies number from the return stack to the stack.

RDROP - drops the value from the return stack.

TMR@ - reads the current value of the real-time clock. (32-bit)

2@ 2! 2CONSTANT 2VARIABLE D+ DNEGATE D< D= - for 32-bit numbers. (thanks to _random)

--> - Used only when interpreting code from a floppy. Logically connects the current block to the next.

Small system of catching critical errors.

##Small changes:

ACCEPT ( addr <Len | -Len> [0] -- addr)
-Len - does not display the characters will overflow.
0 - displays stars instead of characters.

LOAD - requested block is loaded from a disk in any way.

WORD - The separator is defined as a value 32 (space) and less.

PAGE - after clearing the cursor moves to the 0 0 instead of 1 0.

TIMES - in the intermediate mode can properly perform operations on a stack. Like this: 1 10 TIMES DUP

TYPE - does not output the line if they start higher than the TOP (beyond the limit of available memory).

STRCMP - can be used for sorting.
Returns the following:
0 if the strings are identical. (as before)
1 if the first string is greater than the second. (differing by the code of character)
-1 If the second string more than the first.
