J3/06-172r2 Date: 8 May 2003 To: J3 From: Van Snyder Subject: Feature creep -- regularization of DATA INTRODUCTION C557 [88:5-7] requires the in a [R528 87:29-30] to have primaries that are constants or subobjects of constants, or DO variables of containing s, and requires that each operation shall be intrinsic. C561 poses a similar constraint for subscripts. Interestingly, C553, which is for s that are not within s, the parallel requirement is posed in terms of initialization expressions. It would be simpler in standardese, and perhaps for processors as well, if we reduced the number of expression patterns by requiring that those expressions have to be initialization expressions. Other constraints (C553, C564, C567) are already posed in terms of initialization expressions. EXAMPLE One can write DATA A(SIZE(A)/2) / 42 / but one cannot write DATA (B(SIZE(B)/2,I), I=1,5) / 5*42 / EDITS Edits refer to 04-007. [87:30] Change DO bounds and step to initialization expressions: " \smudge , \smudge \smudge [, \smudge \smudge ] )" [88:5-7] Delete C557 because the revised syntax covers it. [88:12-15] "C561 (R528) In an or that is a , any subscript shall be an initialization expression, and any primary within that subscript that is a shall be a DO variable of this or a containing ." [127:16+] Add to initialization expressions: " (9a) A within a ,"
