Read subroutine and recall it in thermal analysis

Hello everyone,
I have a thermal -transient model in Abaqus with a subroutine.f that recall some variables through the card *FIELD (see below).

*FIELD, VARIABLE=1, AMPLITUDE=Amp_RPM
*INCLUDE, INPUT=Mapped_HTC_20230531.inc
*FIELD, VARIABLE=2, AMPLITUDE=Amp_COOLANT_OUT
WJ_NODES,
*FIELD, VARIABLE=3, AMPLITUDE=Amp_RPM
*INCLUDE, INPUT=Mapped_Velocity_20230531.inc
*FIELD, VARIABLE=4
WJ_NODES, <p_START>

Is it possible in calculx read a subroutine and recall the variableS defined in the subroutine with the card FIELD?

Thank you
