Purpose
Flushes the terminal buffer
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
