QBASIC program to grade a score as "Poor" or "Satisfactory"

The program keeps asking for a score. If the score entered is less than zero, it stops immediately. Otherwise it prints "Poor" for a score below 50 and "Satisfactory" for a score of 50 or above.

REM Program to grade scores
CLS
DO
    INPUT "Enter a score (negative to stop): ", SCORE
    IF SCORE < 0 THEN
        EXIT DO
    END IF
    IF SCORE < 50 THEN
        PRINT "Poor"
    ELSE
        PRINT "Satisfactory"
    END IF
LOOP
END

How it works:

• The DO ... LOOP repeats so that many scores can be graded one after another.
• INPUT reads a score from the keyboard.
• If SCORE < 0, the EXIT DO statement ends the loop and the program stops.
• The IF ... ELSE statement tests the score: below 50 prints Poor; equal to or above 50 prints Satisfactory (since 50% is the boundary and belongs to Satisfactory).

Alternative using GOTO (also acceptable):

CLS
Start:
INPUT "Enter a score: ", SCORE
IF SCORE < 0 THEN END
IF SCORE < 50 THEN PRINT "Poor" ELSE PRINT "Satisfactory"
GOTO Start
