Here it is (not tested !) :

Input:     HL = pointer to name of variable to be found
Output:    AHL = pointer to variable data (length of variable skipped)
           DE = pointer to VAT entry
           If CF, the variable was not found

VAR_GET:
 rst rmov10toop1      ; equ 20h
 rst rfindsym         ; equ 10h
 ret c
 push hl
 xor a
 ld hl,2
 add hl,de
 adc a,b
 pop de
 or a                 ; clear Carry Flag
 ret

Example:

 ld hl,var_name-1
 call VAR_GET
 jp c,notFound
 ...

var_name:
 .db 7,"varname"  ; 7 is the name lenght
