## Data Type

Integer## Default Value

0## Description

When using subroutine FMSMM to compute the matrix product

```
[C] = [D] + [A][B]
```

it is sometimes necessary to shift the matrix [A]
before computing the product [A][B].
This parameter allows [A] to be shifted by MMKA
columns before multiplying with [B].
The effect is as if MMKA columns of 0's were added to the beginning of
[A], to form [0|A].
