The problem may be in logic that sets up this command. I presume you are seeing error 3 and not error 108? What have you already discounted? For example, I'd start by breaking the program on the USE command, issue SET from the command line, and check all the open datasessions and aliases.

(edited due to premature send)

I particularly wonder if you have the alias used exclusively in another datasession. For example,

SET EXCLUSIVE ON
CLOSE ALL
SET SAFETY OFF

CREATE TABLE tmpCALLLOG  (CALLPRIME i)
INDEX ON CALLPRIME TAG CALLPRIME

USE tmpCALLLOG

lo=NEWOBJECT('myForm')

DEFINE CLASS myForm AS FORM
  DATASESSION = 2
  PROCEDURE LOAD
    IF NOT USED('CPRIME')
      USE tmpCALLLOG AGAIN IN 0 ALIAS CPRIME ORDER TAG CALLPRIME DESCENDING
    ENDIF
  ENDPROC
ENDDEFINE
