The result of these operations would be:

4.8.2.3 Job Argument Type Conversion
The safest way to use the Call and GetArgument instructions is to always
make sure that the types match between the two instructions. For
example, if Argument 1 in the Call instruction is a B variable, then the
GetArgument should copy this value into an LB variable. Similarly, if
Argument 2 in the Call Instruction is a P variable, then Get Argument
should copy this value into an LP variable.
In the case where incompatible types are used (e.g. Argument 1 in the
Call Instruction is a P variable and GetArgument tries to set this into an LI
variable), the alarm below will be shown during job execution.
