Syntax

FLUSH


See Also

!, !!, @...SAY, SET TBUFSIZE


Description

The flush command flushes all the characters in the terminal buffer to the terminal. To optimize terminal I/O, the Recital/4GL will buffer terminal I/O until a command that requires user input is issued, or the terminal buffer fills up. The terminal buffer size is determined by the SET TBUFSIZE command.


Example

for i = 1 to 5000
    @13,1 say "Loop " + ltrim(str(i))
    flush
next
