## ftsave

ftsave — Save a set of previously-allocated tables to a file.

## Description

Save a set of previously-allocated tables to a file.

## Syntax

    ftsave "filename", iflag, ifn1 [, ifn2] [...]

## Initialization

"filename" -- A quoted string containing the name of the file to save.

iflag -- Type of the file to save. (0 = binary file, Non-zero = text file)

ifn1, ifn2, ... -- Numbers of tables to save.

## Performance

ftsave saves a list of tables to a file. The file's format can be binary or text.

| Warning
The file's format is not compatible with a WAV-file and is not endian-safe.

## Examples

Here is an example of the ftsave opcode. It uses the file ftsave.csd.
