subroutine dbase_read(H)
! dbase_read reads the input file and sets the run-time flags for the run.
! Note that there are four INDEPENDENT ways to run SIMC.
!
! 1. doing_eep: (e,e'p) subcases:doing_hyd_elast, doing_deuterium, doing_heavy
!
! 2. doing_kaon:(e,e'K) subcases:doing_hydkaon, doing_deutkaon,doing_hekaon.
! which_kaon= 0/ 1/ 2 for Lambda/Sigam0/Sigma- quasifree.
! which_kaon=10/11/12 for Lambda/Sigam0/Sigma- coherent production.
! For bound hypernuclear states, set doing_hydkaon true for ALL
! targets (i.e. treat as a heavy proton) but with targ.Mtar_struck
! and targ.Mrec_struck set appropriatly.
!
! 3. doing_pion:(e,e'p) subcases:doing_hydpi, doing_deutpi,doing_hepi.
! which_pion = 0( 1) gives pi+ (pi-) quasifree production.
! which_pion = 10(11) gives pi+ (pi-) coherent production.
! This sets doing_hydpi true for ALL targets (i.e. treat as
! a heavy proton) but with targ.Mtar_struck and targ.Mrec_struck
! set appropriately.
! Added additional options for which_pion:
! which_pion = 2: gamma* p -> pi+ Delta0, gamma* D -> pi+ Delta0 n, or -> pi+ Delta- p
! which_pion = 3: gamma* p -> pi- Delta++, gamma* D -> pi- Delta++ n, or -> pi- Delta+ p
! More options for pi0:
! set "doing_pizero =1" in input file, then
! which_pion= 0( 1) gives pi0 production from proton (neutron)
! which_pion= 2: gamma* p -> pi0 Delta+
! which_pion= 3: gamma* n -> pi0 Delta0
! set "pizero_ngamma" to 1 or 2 whether you want to detect a minimum of 1 or 2 photons
! 4. doing_phsp:Generate acceptance with radiation and cross section disabled,
! use doing_kaon or doing_pion to set hadron mass, then
! set doing_eep,doing_kaon and doing_pion to FALSE.
! May or may not be properly implemented.
!
! 5. doing_delta:(e,e'p)pi subcases:doing_hyddelta,doing_deutdelta,doing_hedelta.
! Identical to doing_pion, except for changes in mass parameters and
! cross section model. Initial implementation will be for proton target
! only (generation well be general, but cross section model will be
! a 'shortcut' version to start with.
! 6. doing_semi: H(e,e'pi)X (doing_semipi) and H(e,e'k)X (doing_semika)
! 7. doing_rho: H(e,e'rho)p, D(e,e'rho)p, 3He(e,e'rho)p
