I am trying to get in hands the standard ISO IS 7185 for PASCAL. For
the moment I have read many times about the so called "level 0" and got a
question on whether is there another level. IS there such ?? And if so, what
are the differences between level 0 and the others ??
Thanks for your attention, Carlos Augusto Proloreagan@hiyall.enet.dec.com (John R. Reagan) (10/30/90)

The only difference is conformant arrays. They are included in Level 1, but not in Level 0. --- John Reagan Digital Equipment Corporation reagan@hiyall.enet.dec.com Disclaimer: The opinions and statements expressed by me are not necessarily those of Digital Equipment Corporation. ---

They differ in one thing only: level 1 implements conformant array parameters, ie. the possibility for a procedure to take arrays of different sizes as parameters. A procedure-heading using conformant arrays might look like this: procedure multiply (var A : array[LoARo..HiARo : Positive; LoACo..HiACo : Positive] : of integer; var B : array[LoBRo..HiBRo : Positive; LoBCo..HiBCo : Positive] : of integer; var C : array[LoCRo..HiCRo : Positive; LoCCo..HiCCo : Positive] : of integer); As you see, this makes it possible to make a general procedure for matrix-multiplication.
