Hello, I was trying to use DSEG and CSEG but I'm having some trouble, please take a look:

    dseg
DL:     db  1
DH:     db  1
    cseg
        mov a,DL    ;Just for test
end

Compiler says:

MCS-51 Family Macro Assembler ASEM-51 V1.3

dsegtest.asm(2): only allowed in CODE segment
dsegtest.asm(3): only allowed in CODE segment

             2 errors detected

I though "OK, if it is just in code segment, then, put on code segment"

    cseg
DL:     db  1
DH:     db  1

        mov a,DL    ;Just for test
end

Compiler says:

MCS-51 Family Macro Assembler ASEM-51 V1.3

dsegtest.asm(5): segment type mismatch

             1 error detected

What I'm doing wrong? Thanks.
