printarray

Print the contents of an array.

Plugin opcode in emugens.

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.
