10.6.1.0742 AT-XY
( u1 u2 -- )
進行實作相依步驟, 因而下一個顯示的字元將出現於使用者輸出裝置的行 u1, 列 u2, 這裝置的左上角是行零, 列零. 如果這項操作不能用指定的參數進行於使用者輸出裝置, 將會有模稜兩可的情況存在.
10.6.1.0742 AT-XY
( u1 u2 -- )
Perform implementation-dependent steps so that the next character displayed will appear in column u1, row u2 of the user output device, the upper left corner of which is column zero, row zero. An ambiguous condition exists if the operation cannot be performed on the user output device with the specified parameters.
See:
A.10.6.1.0742 AT-XY
10.6.1.1755 KEY?
( -- flag )
如果一個字元被提供, 回傳真. 否則, 回傳假. 如果在第一個正確的字元前提供非字元鍵盤事件被提供, 它們將會被丟棄, 而後來不提供. 這個字元必須被下一個 KEY 的執行來傳回.
在 KEY? 傳回一個真之後, 以後的在 KEY 或 EKEY 執行之前的 KEY? 也回傳真, 而不丟棄鍵盤事件.
10.6.1.1755 KEY?
( -- flag )
If a character is available, return true. Otherwise, return false. If non-character keyboard events are available before the first valid character, they are discarded and are subsequently unavailable. The character shall be returned by the next execution of KEY.
After KEY? returns with a value of true, subsequent executions of KEY? prior to the execution of KEY or EKEY also return true, without discarding keyboard events.
See:
A.10.6.1.1755 KEY?
10.6.1.2005 PAGE
( -- )
移到另一頁來輸出. 實際的功能依據輸出裝置. 在一個終端機, PAGE 清除螢幕並重設游標到左上角. 在一個印表機上, PAGE 進行一個格式提示(譯註: 換頁符號).
10.6.1.2005 PAGE
( -- )
Move to another page for output. Actual function depends on the output device. On a terminal, PAGE clears the screen and resets the cursor position to the upper left corner. On a printer, PAGE performs a form feed.
10.6.2.1305 EKEY
( -- u )
接收一個鍵盤事件 u. 鍵盤事件的編碼是實作自訂的.
參閱:
10.6.1.1755 KEY? ,
6.1.1750 KEY ,
A.10.6.2.1305 EKEY
10.6.2.1305 EKEY
( -- u )
Receive one keyboard event u. The encoding of keyboard events is implementation defined.
See:
10.6.1.1755 KEY? ,
6.1.1750 KEY ,
A.10.6.2.1305 EKEY
10.6.2.1306 EKEY>CHAR
( u -- u false | char true )
如果鍵盤事件 u 對應於一個在一個實作自訂字元集的一個字元, 回傳這個字元和真. 否則回傳 u 和否.
10.6.2.1306 EKEY>CHAR
( u -- u false | char true )
If the keyboard event u corresponds to a character in the implementation-defined character set, return that character and true. Otherwise return u and false.
10.6.2.1307 EKEY?
( -- flag )
如果一個鍵盤事件被提供, 回傳真. 否則回傳假. 這個事件必須被下一個 EKEY 的執行傳回.
在 EKEY? 回傳一個真值後, 在 KEY, KEY? 或 EKEY 執行之前伴隨發生的 EKEY? 執行也回傳真, 參考相同的事件.
10.6.2.1307 EKEY?
( -- flag )
If a keyboard event is available, return true. Otherwise return false. The event shall be returned by the next execution of EKEY.
After EKEY? returns with a value of true, subsequent executions of EKEY? prior to the execution of KEY, KEY? or EKEY also return true, referring to the same event.
10.6.2.1325 EMIT?
( -- flag )
如果使用者輸出裝置準備接收資料而取代 EMIT? 執行的 EMIT 將不會 遭受一個無限的延遲, flag 為真. 如果裝置狀態是未決定的, flag 為真.
10.6.2.1325 EMIT?
( -- flag )
flag is true if the user output device is ready to accept data and the execution of EMIT in place of EMIT? would not have suffered an indefinite delay. If the device status is indeterminate, flag is true.
See:
A.10.6.2.1325 EMIT?
10.6.2.1905 MS
( u -- )
等待至少 u 千分之一秒.
注意: 實際的長度和時間週期的變化依據實作自訂的系統時鐘精確度、 其他系統和電腦的特質, 這在這個標準的範圍之外.
參閱:
A.10.6.2.1905 MS
10.6.2.1905 MS
( u -- )
Wait at least u milliseconds.
Note: The actual length and variability of the time period depends upon the implementation-defined resolution of the system clock and upon other system and computer characteristics beyond the scope of this Standard.
See:
A.10.6.2.1905 MS
10.6.2.2292 TIME&DATE
( -- +n1 +n2 +n3 +n4 +n5 +n6 )
回傳目前的時間和日期. +n1 是秒數 {0...59}, +n2 是分鐘 {0...59}, +n3 是小時 {0...23}, +n4 是日期 {1...31}, +n5 是月份 {1...12}, 而 +n6 是年 (例如, 1991).
10.6.2.2292 TIME&DATE
( -- +n1 +n2 +n3 +n4 +n5 +n6 )
Return the current time and date. +n1 is the second {0...59}, +n2 is the minute {0...59}, +n3 is the hour {0...23}, +n4 is the day {1...31} +n5 is the month {1...12}, and +n6 is the year (e.g., 1991).
