## passign

passign — Assigns a range of p-fields to ivariables.

## Description

Assigns a range of p-fields to ivariables, or i- or k-array.

## Syntax

     ivar1, ... passign [istart][, iend

     iarray passign [istart][, iend

     karray passign [istart][, iend

## Initialisation

The optional argument istart gives the index of the first p-field to assign. The default value is 1, corresponding to the instrument number.

The optional argument iend gives the index of the last p-field to assign. The default value is 0, which means all.

One of the variables can be a string variable, in which case it is assigned the only string parameter, if there is one, or an error otherwise.

## Performance

passign transfers the instrument p-fields to instrument variables, starting with the one identified by the istart argument. There should not be more variables than p-fields, but there may be fewer.

passign can transfer the instrument p-fields to a one dimensional array, either an iarray or a karray.

## Example

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