Read-Only Author Li Li Posted 27-Apr-2004 09:38 GMT Toolset C51	The length of segment ?STACK Li Li LINK MAP OF MODULE: 6H (DISPBIOS) TYPE BASE LENGTH RELOCATION SEGMENT NAME ----------------------------------------------------- IDATA 005DH 0001H UNIT ?STACK Q:How was the length of segment ?STACK calculated?
Read-Only Author V K Posted 27-Apr-2004 11:04 GMT Toolset C51	RE: The length of segment ?STACK V K The length and of segment stack isn't calculated! It is defined in the STARTUP.A51, like this: ?STACK SEGMENT IDATA RSEG ?STACK DS 1 By default L51 locates stack in the end of IDATA memory, and phisical size is RAMTOP-STACK = 0ffh( or 07fh for 51)- 005DH = 162 (or 34) bytes.
Read-Only Author Li Li Posted 28-Apr-2004 01:53 GMT Toolset C51	RE: The length of segment ?STACK Li Li Thank you for your reply! The length of segment ?STACK is incorrect or meaningless in the link map? I don't include the startup.a51 in the project! In application,I only pay attention to the base of ?STACK ?

If you are why the #&!! are you mucking whith things that are no business of yours. 3) If you use the tools as intended you do not need to "pay attention to the base of ?STACK " SO, instead of using the tools as intended, you have created a mess where you have to do the work the tools are designed to do for you.
