Hi folks:

I'm using

GNU Pascal version 20000707, based on gcc-2.95.2 19991024 (release). Copyright (C) 1987, 1989, 1992-2000 Free Software Foundation, Inc.

while my student Ryan is using:

GNU Pascal version 2.1 (20020510), based on gcc-2.95.3 20010315 (release). Copyright (C) 1987-2002 Free Software Foundation, Inc.

I have no problem compiling with

 gpc --standard-pascal \
  --transparent-file-names \
  --no-mixed-comments \
  -O0 \
  -Wall \
  $program.p -o $program

but Ryan has trouble compiling a program that has a call to the page() function:

alist.p:3960: undeclared identifier `Page' (first use in this routine)

To my surprise, this is listed:

http://www.gnu-pascal.de/gpc/Page.html

as "Page is an ISO 10206 Extended Pascal extension."

Did GPC change between these compilers? Does the use of page() mean I cannot use --standard-pascal ? page() was in the original book! It is listed on page 105 (Appendix A) as a standard procedure!

Yes, the GPC docs are wrong, `page' is ISO 7185.

GPC 20020510 is outdated. The problem with `page' is apparently fixed in newer versions (tested with 20040516), so Ryan may consider upgrading. Some incompatible syntax changes happened meanwhile (e.g. asmname), but they shouldn't affect ISO compliant code which you seem to be using.
