2. Can you tell me my grammar for this function command？
3. Where can I learn Pspice function commands and their syntax

Pspice is coming with a user guide and reference manual.
The keyword is "scheduling changes to runtime parameters". The manual example is:

.OPTIONS RELTOL={SCHEDULE( 0s,.001,2s,.005)}
