8BASIC theory 4/6: Statements I

8BASIC (C) is a BASIC interpreter developed by manufacturer G.G in 2010 for the homemade Z80/AM95 8 bit NANO COMPUTER.

 

 

STATEMENTS

 

8BASIC consists of 51 fixed-format statements.

 

During editing you can change any of the 26 letters of each variable in any of the 51 statements.

 

1 "IF A>B:N" ; jump to line label N if A is greater than B

2 "IF A=B:N" ; jump to line label N if A is equal to B

3 "IFAB:N" ; jump to line label N if A is not equal to B

4 "IFA>=B:N" ; jump to line label N if A is greater than or equal to B

5 " "N": " ; line label N marking the destination of a GoTo/GoSub statement

6 "GO TO N " ; jump unconditionally to line label N

7 "GO SUB N" ; temporarily jump to line label N and returning to the following line

8 "RETURN " ; jump back to the statement following the original GOSUB statement

9 " END " ; terminate the execution of the program and suspends CPU operation

10 "Z=X+Y " ; add X and Y and assign the result to Z

11 "Z=X-Y " ; subtract Y from X and assign the result to Z

12 "Z=X*Y " ; multiply X and Y and assign the result to Z

13 "Z=X/Y " ; divide X by Y and assign the result to Z

14 "Z=SQR(X)" ; assign to Z the square root of X

15 "Z=INT(X)" ; assign to Z the integer of X

16 "Z=ABS(X)" ; assign to Z the absolute value of X

17 "Z=NEG(X)" ; assign to Z the value of X and change sign of Z

18 "Z=SGN(X)" ; assign to Z the sign function of X

19 "Z= (X)^Y" ; assign to Z the result of X raised to the power of Y

20 "Z=EXP(X)" ; assign to Z the result of e raised to the power of X
