# equations
a'=3 - 2*a - 2.5*a*b
b'=2*a - 2.5*a*b
c'=2.5*a*b - 3*c
d'=2.5*a*b - 4*d

# initial condition
init a=0, b=0, c=0, d=0

# final time
@ total=4
# set the plotting window size:
@ xlo=0, xhi=4, ylo=0, yhi=1

# run the simulation in the GUI by selecting (I)nitialconds|(G)o
# plot species b,c, and d by selecting (G)raphic stuff|(A)dd curve and 
# assigning the y-axis
