How to get output variable PEEQT with GETVRM?

Hello everyone!

I want to get the output variable PEEQT using GETVRM in the USDFLD. 

I wrote a Fortran subroutine as following:

CALL GETVRM('PEEQT',ARRAY,JARRAY,FLGRAY,JRCD,JMAC,JMATYP,MATLAYO,LACCFLA) 

But the error is: 

"Output request peeqt is not available for this option. The analysis has terminated due to previous errors. Abaqus/Standard Analysis exited with an error - Please see the message file for possible error messages if the file exists."

Can anyone help on this one? 

Thanks in advance
Regards,

Javier
