I write on Fasmw 1.73

I want do macro auto regs or mem.
Lets say macro SmartReg
Code:
Sreg 10 ;do mov r13,10. And do EQU regNum+1
Sreg 20 ;do mov r14,20
Smov  rax ;do mov rax,r14
Sreg 30 ;do mov r15,30
Smov  [rdx] ;do mov [rdx],r15
Sreg 40 ;do mov [r16],40  to mem r16
Sreg 50 ;do mov [r17],50  to mem r17
Sreg 60 ;do mov [r18],60  to mem r18
Sreg 40 ;do mov [r19],40  to mem r19
Sreg 80 ;do mov [r20],80  to mem r20
Smov  rax ;do mov rax,[r20]
EndReg ;set EQU regNum-1
Smov  rcx ;do mov rcx,[r19]

Any example of real world task where this could be useful would be great.

Also the logic behind the macro is unclear from your example.

Interesting idea to use some kind of own stack, but do not touch the registers.
It can be implemented as macros:
mypush <something>
mypop <something>
Without any worries about stack address or operations quantity. Without size limits of original push-pop. It can be some cyclic buffer as well

I try do this. Work ok
Code:
r16 EQU [memR16]
r17 EQU [memR17]
r18 EQU [memR18]
macro SmrtReg chV { mov FirstSreg,chV
                  FirstSreg equ FirstSreg + 1 }
.data 
        memR16 dq 0
        memR17 dq 0
        memR18 dq 0

.code
        FirstSreg equ r13
        mov     eax,dword r16 ;do mov eax,dword [memR16]
        SmrtReg 10  ;this ok do mov     r13, 10
        SmrtReg 10  ;this get me error: r13+1

    


But my problem increase FirstSreg. Fasm get me error: r13+1
I want get r14 but not r13+1
