DCL:GRPH1:SLPACK: Layout Routines:Explanation of Main Subroutines

4.3.1 slinit

1.

Function

Initializes the layout subroutine package. In GRPH1, it is called internally by sgopn (Actually by sginit; See Section 2.4.1), so the user does not have to call it directly.

2.

Call

NumRu::DCL.slinit(wxmax,wymax,fact)

3.

Explanation of Parameters

wxmax, wymax	(R)	The maximum frame (given in units of the WC).
fact	(R)	Gives the ratio between the unit length in WC and the actual length.

4.

Notes

(a) Must be

wxmax>0, wymax>0, and fact>0.

(b)

When this routine is called, the maximum frame is allotted to the level-1 frame. The level-1 frame can be changed using slsize or slform.
