obsolete: Just use Set_attribute DF_FILE_STATUS inactivates a record by putting 0 in the buffer
// Inactivate Df_File {KEEP}
// if {KEEP} then we put the original rec back in buffer
#IF !0>1
#CHECK !2 "KEEP"
Send Inactivate to DESKTOP !1.File_Number 1
#ELSE
Send Inactivate to DESKTOP !1.File_Number 0
#ENDIF
