Rewind a sequential file to the beginning |
SYNTAX
rewind #channel [, #channel]…
Rewinds the sequential file(s) open on the channel(s) specified.
If the file is open in read mode, the next get[field] # command reads from the beginning of the file. If the file is open in create or append mode, the next put[field] # overwrites the beginning of the file. Rewinding a file does not truncate it.
#channel |
The channel number must be an integer expression in the range 1-64. It is the number that was allocated to the file when it was opened (using open #). It may be a constant, field name or expression. |
NOTES
The seek # command is used to position a file at any point.
The wind # command positions a file at the end.
If the channel is closed the command is ignored.
EXAMPLE
rewind #2, #3
