-## Language reference
-
-### List of the commands
-
-* **CLS** clear screen and move cursor 
-
-* **DUMP [ARRAYS|VARS]** debug info of BASIC memory, variables and arrays
-
-* **LIST** inputed program listing
-
-* **LOAD** load program from EEPROM
-
-* **NEW** clear BASIC memory
-
-* **RANDOMIZE** initialize pseudo-random number generator
-
-* **RUN** run inputed program
-
-* **SAVE** save current program into EEPROM
-
-### Variables declaration:
-
-**LET** ABC = 3
-> declares ABC real number variable (single precision)
-
-**LET** Y% = 4
-> declares integer variable [-32768; 32767]
-
-**LET** SS$ = "HELLO, WORLD"
-> declares string variable
-
-**LET** RES! = A<B -=""> declares logical variable
-
-### Aray declaration
-
-**DIM** AB%(3,3,3)
-> declares 3 dimensional array with each dimension from 0 to 3 of integer data
-
-### Aritmetics
-
-**LET** A=3.0:**LET** B=2.0
-
-**PRINT** (A+B)^(A*B)
-> prints 15625.00000000
-

-```basic
-
-10 PRINT "MULTIPLICATION TABLE"
-20 FOR I%=1 TO 9 STEP 1
-30 FOR J%=1 TO 9 STEP 1
-40 GOSUB 100
