Hold it!
If you go into DEBUG and use the 'A' command(rest assured, debug is NOT my
assembler), type 'JMP NEAR 100' and press enter twice, then use the 'U'
command, you get something like this:

20B4:0100 E9FDFF        JMP     0100
20B4:0103 F8            CLC
20B4:0104 1910          SBB     [BX+SI],DX
20B4:0106 4F            DEC     DI
20B4:0107 0E            PUSH    CS
20B4:0108 0000          ADD     [BX+SI],AL
20B4:010A 10EF          ADC     BH,CH
20B4:010C 00F0          ADD     AL,DH
20B4:010E 46            INC     SI
20B4:010F 32B210B2      XOR     DH,[BP+SI+B210]
20B4:0113 034F0E        ADD     CX,[BX+0E]
20B4:0116 2D2F00        SUB     AX,002F
20B4:0119 FD            STD
20B4:011A 46            INC     SI
20B4:011B 36            SS:
20B4:011C 99            CWD
20B4:011D 00A3201E      ADD     [BP+DI+1E20],AH

If JMP NEAR executes like you did, this would jumo ti 20B4:FDFF instead of
20B4:100.
