By default, XA80 takes enclosing brackets and turns them internally into square brackets to represent indirection. For example:

    LD  A,(base+(offset*7))    // Source line where base=200, offset=5
    LD  A,[235]                // Gets turned into this

However, some legacy 8080 code uses this to signify a calculation (the 8080/8085 don't use brackets of any sort for indirection). For example:

    lxi h,(nxtrec-reccnt)	;HL=.fcb(nxtrec)

The above shouldn't automatically get turned into redirection.
