| 6!:1 y | Session. Seconds since start of session |
| [x] 6!:2 y |
Execute. Seconds to execute sentence y
(mean of x times with default once). For example: a=:?50 50$100 6!:2 '%.a' 0.091 10 (6!:2) '%.a' Mean time of 10 executions 0.0771 ts=: 6!:2 , 7!:2@] Time and space ts '%.a' 0.08 369920 |
| 6!:3 y | Delay. Delay execution for y seconds. For example, 6!:3 (2.5) |
| 6!:8 y | Query Clock Frequency. Return the clock frequency,
the number of clock counter values per second. (In Windows, the result
of QueryPerformanceFrequency.)
The argument y is ignored.6!:8 '' 1.19318e6 |
| 6!:9 y | Query Clock Counter. Return the current clock counter

| 6!:10 y | Performance Monitor Data Area. Literal (character) vector y
is to hold the fixed-sized
records of "packed" performance monitor data; the old PM data
area (if any) is released. The PM counter
(see 6!:12) is set to 0. If y is an empty vector,
no PM data will be collected. x is a 2-element vector of control parameters; 0 0 is assumed if it is elided. 0{x - what to record 0 - entry and exit 1 - entry and exit and all lines 1{x - action on running out of space in y 0 - "wrap", discard the oldest record 1 - "truncate", discard the newest record The result is the number of records that will be held in y. |
| 6!:11 y | Unpack PM Data. Unpack the PM data, resulting in a boxed vector
of data columns: 0 name 1 locale where name is found 2 valence 3 line number (_1 for entry; _2 for exit) 4 space in use (bytes) 5 time (seconds) 6 list of names Columns 0 and 1 are indices into column 6. Columns 0 to 5 have the same number of (corresponding) elements. y are indices of the rows to be unpacked, where 0 is the oldest row (and _1 is the newest row). All rows are selected if y is the empty vector. Rows in the result are always arranged from oldest to newest and no row is selected more than once. |
| 6!:12 y | Add y to the PM Counter. PM data is recorded if the PM
counter is greater than 0
and a PM data area is extant. (A non-empty PM data area
must be specified before the PM counter can be changed.)
The result is the value of the PM counter after the operation. |
| 6!:13 y | PM Statistics.
Produces a 6-element vector of the following information: 0 - what to record 0 - entry and exit 1 - entry and exit and all lines 1 - action on insufficient space 0 - wrap 1 - truncate 2 - the maximum number of records 3 - current number of records 4 - whether records have been lost 5 - current value of the PM counter If no PM data area has been specified the result is 6$0. The argument y is ignored. |
