Basic Examples  (2)

Run a command until a memory limit is exceeded:

The loop ran until memory allocation for the result of Range exceeded the limit:

Scope  (2)

Specify the value to return if the time constraint is reached:

Use CheckAbort inside MemoryConstrained to select which parts are skipped if the limit is reached:

Properties & Relations  (4)

The third argument is only evaluated if the memory limit is reached:

A nested AbortProtect can block the action of MemoryConstrained:

An enclosing AbortProtect is overridden by MemoryConstrained:

While code inside the MemoryConstrained is terminated, AbortProtect runs to completion:

MemoryConstrained can constrain the first argument of CheckAbort, but not the second:
