BASIC-DOS

BASIC-DOS BASIC Commands

GOTO

The GOTO statement transfers control to another line:

GOTO label

where label is the line number of a line within the current program.

Example:

LET R = 1
10 PRINT "R ="; R, "AREA ="; 3.14 * R^2
LET R = R + 1
IF R <= 3 THEN GOTO 10

R = 1   AREA = 3.14
R = 2   AREA = 12.56
R = 3   AREA = 28.26

Differences from Microsoft BASIC

BASIC-DOS does not require all lines within a program to begin with a line number. Only those lines that are the target of a GOTO (or GOSUB, RESUME, etc) must be numbered, and line numbers don’t need to be in any particular order.

When an error occurs on a numbered line, error messages report the line number (eg, “Syntax error in line 1160”).
