Set GPRM Command

The set GPRM command is used to determine a value that is then placed in a GPRM
location. There are four elements to set:

The operation type: There are 11 operations you can choose from, ranging from a simple

move to a “bit-wise exclusive or.” See

Operation Types

for details on using these


The source type: You choose from five possible source element types that can be used

as the source. See

Source Element Types

for details on the element types.

The source value: Once you choose the source element type, you can then choose the

actual element. For example, if you choose an SPRM element type, you use this setting
to choose the specific SPRM to use as the source.

The GPRM target: You choose a GPRM location where the value gets written. Depending

on the operation you choose, this GPRM location may also be the second value in a
math operation. For example, if you choose a subtraction operation, the source value
is subtracted from the current target value and the result is written to the target location.
