Assume that we had called the same process ID 5 times like so 0 0 0 0 0 when we get to that fifth call, since it's already in memory, should we increase the time? like should it be 0, 1, 2, 3, 4 or 0, 1, 2, 3, 3 (since were not moving values from Virtual...

hey just a quick clarification, does the arguments like arg0, arg1, ... also add towards the max 50 identifier count?

okay, so I can assume that the arguments will be accessed under the alias arg0, arg1, .... and not under any other name correct? but wouldn't this contradict the statement where identifier names can only include lowercase alphabetic order?

Taking this into consideration from the ml language 6. there will be at most 50 unique identifiers appearing in any program lets just say a variable within a function is introduced, and then is set out of scope when exiting the function. The variable ...

so, i saw that in the steps to run and execute ml files, we basically turn the ml file into a c file, compile it, and execute the program. However, it also says to delete the c file and executables after running a program, so does it even matter if i ...
