Can some one explain when it is a "MUST" to us these commands and other similar ones like ASYDL, ASYDN.... in SV8500???

ASYD assign system data
ASYDL assign local data memory
ASYDN assign network data memory

if your system working as standalone system used ASYDL
if you have FCCS or CCIS used ASYDN

in some cases you should apply ASYDL and ASYDN at the same time

thanks for your reply...!
May you give more details about the "cases that I should apply ASYDL ASYDN at the same time"? and is that valid for the other similar commands or ONLY for ASYD?

i mean when you apply for example ASPA command and try to test your programming you will find does not working at this time you need to do ASPAL and ASPAN

in General in standalone system you need ASYD and ASYDL and every command with last letter is L

in Network node you need ASYDN and every command with last letter N
