运行程序是出现forr1:severe (66):output statement overflows record unit 10提示

原程序代码为：

PROGRAM TEST1211
IMPLICIT NONE

CHARACTER(256) :: FileName
CHARACTER(41) :: Sta
INTEGER :: Round

PRINT *, '请输入要统计的球队名称：'
READ(*, *) FileName
OPEN(UNIT = 10, FILE = TRIM(FileName), FORM = 'FORMATTED', ACCESS = 'DIRECT', RECL = 76)
PRINT *, '开始建立数据文件'
PRINT *, '请依次输入球队的胜负，比分，得分王，篮板王，助攻王[键入EXIT可结束输入]:'
Round = 0
DO
Round = Round + 1
WRITE(*, '(1X, "请输入第", I2, "轮统计数据:")') Round
READ(*, '(A4:1X, A7, 3(1X, A10))') Sta(1:4), Sta(5:11), Sta(12:21), Sta(22:31), Sta(32:41)
IF('EXIT' == Sta(1:4)) THEN
EXIT
ENDIF
WRITE(10, 100, REC=Round) Sta(1:4), Sta(5:11), Sta(12:21), Sta(22:31), Sta(32:41)
100 FORMAT("胜负：", A4, 1X, "比分：", A7, 1X, "得分王：", A10, 1X, "篮板王：", A10, 1X, "助攻王：", A10)
ENDDO
CLOSE(10)

END PROGRAM TEST1211

如果我将RECL的值改大些，比如100,则可运行，但我觉得RECL设为76已经足够，不解其故，求各位大神，大侠解答
