Hello, I am facing a strange problem while running a SAC Macro. The output
is correct and the macro is performing but showing the strange error.

**The Macro is:*
r $dat
evaluate to tstart &1,dist / 8.
evaluate to tdeb &1,dist / 3.0
evaluate to tfin %tdeb + 201
if &1,delta gt 1
evaluate to tadd &1,delta * 201
evaluate to tfin %tdeb + %tadd + 10
endif
evaluate to tbid &1,dist / 2.5
if %tbid gt %tfin
evaluate to tfin %tbid
endif
cut %tstart %tfin
---------------------------------------------------------------------------------------------------------------------
*The output is**:*
