Earlier in fico version 1.18.05 i was using one algorithm called XPRS_TOP for LP optimization now this version has mosel version of 2.2.0 and optimizer version of 18.10.00. Now in new version which
it gives me the error saying XPRS_TOP is not defined while documentation its stated its a algo given by fico itself this newer version has mosel version of 6.4.1 and optimizer version of 42.01.01
plzz help me how to solve this issue or any other algo that i can use in place of XPRS_TOP
plzz do help me its urgent

A bit more context would be helpful.
I suspect you are using this as argument to function maximize or minimize in order to stop right after the solving the LP? In that case the documentation says the new constant for this is XPRS_LPSTOP. Can you please check the documentation and see whether this option is what you want?
yaa u r right i am using it along with maximize and minimize
minimise(XPRS_TOP,Objective)
this is how i am using it
The option XPRS_TOP for the minimize/maximize subroutines of mmxprs has been replaced by the option XPRS_LPSTOP, to continue the MIP search from this point you can invoke the minimize/maximize statement a second time, specifying the option XPRS_CONT (using this option was not a requirement in Mosel releases prior to 3.2 (Nov 2010), when this change was made).
