| Length of input record | MAX_INT |
| Length of output record | Unlimited |
| Length of source line | Unlimited |
| Number of fields in a record | MAX_LONG |
| Number of file redirections | Unlimited |
| Number of input records in one file | MAX_LONG |
| Number of input records total | MAX_LONG |
| Number of pipe redirections | min(number of processes per user, number of open files) |
| Numeric values | Double-precision floating point (if not using MPFR) |
| Size of a field | MAX_INT |
| Size of a literal string | MAX_INT |
