Global Variable in Fox Code?

Question

Via a Parameter Group, I am trying to copy existing records.  During the copy I am trying to replace one characteristic with a sequencial number.  However, during a single execution of the parameter group, the variable is being reset to it's initial value after each new record is created.
Is there a way to store the value of a variable so sequencial numbering can be achieved?
Thank you in advance for any suggestions or advice!

Include characteristic HIRE in your 'fields to be changed' of planning function and in FOX write:
DATA L_HIRE TYPE HIRE.
DATA EXISTBPSID TYPE ZTA_BPSID.
DATA BPSIDNO TYPE ZTA_BPSID.
BPSIDNO = VARV(BPSTAS2).
FOREACH L_HIRE.
IF EXISTBPSID = '#'.
{L_HIRE,BPSIDNO} = {L_HIRE,EXISTBPSID}.
BPSIDNO = BPSIDNO + 0000000001.
ENDIF.
ENDFOR.
