Print 2 strings in a box in emu8086

I have a code that does more or less what I need that is what I have been trying to edit so that I can put two strings in ved of only 3 digits, some solution?

.model small
.stack 200h
.data
line db '***********$'
nl1 db 0ah,0dh,'*         *'
nl2 db 0ah,0dh,'*         *'
nl3 db 0ah,0dh,'*         *'
nl4 db 0ah,0dh,'*         *'
nl5 db 0ah,0dh,'*         *'
nl6f db 0ah,0dh,'*    '
val db ?
nl6l db '    *'

nl7 db 0ah,0dh,'*         *'
nl8 db 0ah,0dh,'*         *'
nl9 db 0ah,0dh,'*         *'
nl10 db 0ah,0dh,'*         *'
nl11 db 0ah,0dh,'*         *$'
