from the ISO standard:

   6.8.3.9 For-statements.

   "The control variable shall be an entire-variable whose identifier
   is declared in the variable-declaration-part of the block
   closest-containing the for-statement."

ANSI reads the same (by definition and if you look it up).

now if you go back to the second edition user report (by wirth), it
omits any restriction. is that what you mean by standard pascal?
