! every volume XXXX has an array XXXX that describes the GSVOLU parameters

! and an array ACT_XXXX that describes the action on the volume .GSPOS,GSPOSP

! GSDVN,GSDVN2,GSDVT,GSDVX,OR GSDVT2.

! Format of actions:-

!**** all Character variables in these fields are 4 characters long****

!The first 4 character variable of the action field is 'VOLU','POS ','POSP',

!'DVN ','DVN2','DVT ','DVT2','DVX ' which is equivalent to the call to geant

!subroutines GSVOLU, GSPOS etc.

!The order of the variables is the same as in the geant subroutine call except

!for the following exceptions. If one is performing the action on a volume name

!(say 'CEM1'),

!that information is contained in the array name (ACT_CEM1),

!so it is not repeated in the action field. Also, in the acse of variable

!parameters as in the VOLU and POSP actions, the number of parameters (NPARS)

!is declared before tha parameters themselves. This is opposite to that in the

!subroutine call. The reader should read the geant geometry manual for a

!complete specification of the other variables.
