I'm using EDSIM51 on MacOS. But I'm always getting Invalid Label - **** is keyword errors. Read documentation (User's Guide and Examples pages) but still no idea where I'm making mistake. I've downloaded example codes from Edsim's website, but it's giving same error for their official examples.
For example, This is an LCD example which taken from their website:
; put data in RAM
MOV 30H, #'A'
MOV 31H, #'B'
MOV 32H, #'C'
MOV 33H, #0 ; end of data marker

; function set sent for first time - tells module to go into 4-bit mode

Can you please tell me what is I'm missing?
