Creating a ramdisk from another block device

RAMDISK$(string-expression)

Creates a RAM-backed block device from the content of an existing block device. The parameter is the name of the source device (e.g. "hd0"). Returns the name of the new RAM disk device as a string.

Examples

REM Duplicate an existing block device into RAM
ram$ = RAMDISK$("hd0")
PRINT "Created RAM disk: "; ram$

Notes

The new device is a complete in-memory copy of the original device.
Useful for testing, running faster I/O, or working on a safe copy.
RAM disks are volatile: contents are lost when the system is rebooted or the device is discarded.

Creating blank ramdisks

RAMDISK(integer-expression, integer-expression)

Creates a new RAM-backed block device with the given dimensions.

First parameter = number of blocks.
Second parameter = block size in bytes.

The device is initially unformatted and cannot be mounted until a filesystem is created on it. Returns the name of the new RAM disk device as a string.

Examples

REM Create a 10 MB RAM disk with 512-byte blocks
ram$ = RAMDISK(20480, 512)
PRINT "Created RAM disk: "; ram$

Notes

Size = blocks × blocksize.
Device names are automatically assigned by the system (e.g. "ram0", "ram1").
Contents are volatile and cleared when the system shuts down or discards the device.
