memory is not the same?

for 'local' variables at the top of the program define them like:
onebyte equ TEXT_MEM
twobytes equ TEXT_MEM+1
threebytes equ TEXT_MEM+3

get it? start at TEXT_MEM and then add to the offset after each new one you
'allocate'

the external variables is harder to do

 ld hl,var_info
 rst 20h
 ld hl, code_end - code
 call $472F
 ld a,b
 ex de,hl
 call $4c3f
 call _SET_ABS_DEST_ADDR
 xor a
 ld hl,code_end - code
 call _SET_MM_NUM_BYTES
 xor a
 ld hl,code
 call _SET_ABS_SRC_ADDR
 call _mm_ldir

var_info:
.db $xx,$x,"name"         ;first byte is the variable type 2nd is the name
length 3rd is the name

code:
 .db numbers,"strings and stuff too if its a program or string"
code_end:
