How to scale a section of a lens system from within ZPL?

And the general solution if more parameters are involved:

Use SPRO to get the surface data and scale them, then use SETSURFACEPROPERTY to set up the scaled data.

Since not all parameters are needed to modify, you can build a vector and put the type codes to be scaled into this vector and call it every time.

Here is an example

!put the data into a vector

vec1(1)=2

vec1(2)=3

vec1(3)=5

vec1(4)=6

vec1(5)=10

for i=1,5,1

!call data out of the vector

k=vec1(i)

next

Here is an example of SETSURFACEPROPERTY

Set the thickness of surface 2 to the thickness of surface 1

SETSURFACEPROPERTY 2, THIC, THIC(1)

! Set the value of parameter 4 on surface 11 to 7.3

SURP 11, PARM, 7.3, 4
