## printarray

printarray — Print the contents of an array

## Description

Plugin opcode in emugens.

Prints the contents of an array

## Syntax

    printarray ixs[] [, Smft, Slabel ]

    printarray kxs[] [, ktrig, Sfmt, Slabel ]

## Initialization

Sfmt - If given, it is passed to printf for each element of the array. Otherwise a default format is used

Slabel - If given, it is printed before the contents of the array, to easily identify the data

## Performance

ktrig - The array will be printed whenever this value changes from 0 to possitive. Can be used together with metro to print at a given time interval. A value of -1 indicates to print at each k-cycle (default = 1)

## Examples

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