SETSURFACEPROPERTY, SURP
Sets properties of surfaces.
Syntax:
SETSURFACEPROPERTY surface, code, value1, value2 SURP surface, code, value1, value2
Discussion:
Surface is an expression that evaluates to an integer specifying the surface number. The code may either be an expression that evaluates to an integer or a mnemonic which specifies what property of the surface is being modified. The third and fourth arguments are the new values for the specified property, and they may be either text in quotes, a string variable, or a numeric expression, depending upon the code. For most codes, the property value being modified is defined by the value1 argument. A few operands require both a value1 and a value2, as described in the table below.
If the property being modified is under control of the Multi-Configuration Editor, then the multi-configuration data for the current configuration only will also be modified to reflect the changed property.
To set a surface as the stop surface, see "STOPSURF".
SURP is a shorthand for SETSURFACEPROPERTY and is functionally identical.
| Code | Property | |
| Basic Surface Data. See "Lens Data. | ||
| 0 or TYPE |
Surface type. The value should be the name of the object, such as "STANDARD" for the standard surface. The names for each surface type are listed in the Prescription Report in the Surface Data Summary for each surface type currently in the Lens Data Editor. See also "Surface names" summary table at the bottom of this page. To change the surface type to a user defined surface, first set the DLL name using code 9 (SDLL), then set the new surface type to USERSURF. See also Code 17. |

Changes to surface properties usually require that a subsequent UPDATE (see "UPDATE") be performed to update pupil positions, solves, and other data required for correct ray tracing. The UPDATE is not performed automatically because it is faster to execute all SETSURFACEPROPERTY keywords and then execute just one UPDATE. The function SPRO uses a very similar syntax and identical code values to "get" rather than "set" these same values.
Example:
! Set the glass type on surface 7 to BK7 SETSURFACEPROPERTY 7, GLAS, "BK7" ! 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
