yes. seems everything is working most excellently. i have no clue how to thank you enough! so, i extend glorious amounts of thanks to you, and everyone else who replied - it's been a giant help. i even book marked that ebook that was linked to by another monk.

the module Pm::Bc_chef doesn't like having use Pm::User; in it. Well, it actually causes Pm::User to throw the "subroutine not defined" error message (because use Pm::Bc_chef; is in the module Pm::User. so, if chef needs to refer to a user module subroutine, i can't put use Pm::User; in Bc_chef.pm. baffling, but it's working.

so grateful

Btw - is my coding awful? i've always wondered, and hoped you folks might be willing to grade it without killing my itty bitty ego too much... ;) is there more of my code you would like to see? i can let you peek under the hood, so to speak, to get a better feel for how i go about doing things. i'd really like some constructive input on it, too....i know it's way off topic here, so perhaps PM me...I'll be on and off fairly often, doing my (re)search(es).

    Hint, hint: the Offering Plate.

    ... is my coding awful? i've always wondered ... i can let you peek under the hood ... i'd really like some constructive input on it ...

    As a registered user, you have a public scratchpad (see your personal node). You could post code there and solicit comments in the Chatterbox. The scratchpad is limited to 64K, but nobody is going to read anywhere near that much code (not for free, anyway), so don't go crazy. I would post code examples that are complete (or as complete as reasonably possible).

    Update:

    ... hoped you folks might be willing to grade it without killing my itty bitty ego too much ...
    I've seen the code you've posted in this thread. Constructive criticism, offered bluntly, can be pretty bruising. Please don't ask for something you aren't willing to receive.

    nope! things don't seem to be meshing nicely....

    and oh no! @INC will no longer include .! That's inconvenient. But, not impossible to move my modules to a folder in @INC

    Pm::Redir is claiming pre_html_header() isn't defined - this routine is found in Pm::Html

    the subs Pm::Redir::redir and Pm::Redir::redir3 both call Pm::Html::pre_html_header()

    now granted, Pm::Html does use a bunch of other modules i've created. i haven't checked those modules to see if they include Pm::Redir, but would it matter if Pm::Html uses a module which then includes Pm::Redir??

    here's the code:

    just the header to ./Pm::Html
    package Pm::Html; #/ # functions for displaying HTML elements #/ my $DEBUGGER = 0; my $TABLE_BORDER = "0"; ######################## use strict; use warnings; use Exporter; use vars qw($VERSION @ISA @EXPORT_OK %EXPORT_TAGS); use URI::Escape; ######################## use Pm::Bc_chef qw(cookie_get); use Pm::Bc_sql qw(get_race_asWord get_zodiacs get_themes get_constant get_theme_data get_config get_cities get_countries sql_execute get_users get_site_name get_home_page user_exists get_location get_phrase ); use Pm::Bc_misc qw(get_param add_numeric_suffix shorten_str ); use Pm::Date qw(expand_date determine_zodiac get_today get_month ); use Pm::Search qw(search_terms); use Pm::User qw(get_user_stats get_user_friend_requests get_user_blocked_users get_user_unread_messages get_user_stat get_user_fuck_alert_count get_user_pic get_user_dp get_user_stats_asIcons get_user_friends ); ######################## our $VERSION = 1.00; our @ISA = qw(Exporter); our @EXPORT_OK = qw( _tests pre_html_header header footer table fieldset fieldset_constricted div tdata trow radio checkbox textarea unordered_list ordered_list li href img dropdown input display_404_page display_about_page display_chat display_city_names display_city_names_asDropdown display_country_names display_country_names_asDropdown display_forgot_page display_blocked display_friends display_fuck_me_alerts display_homepage display_mail display_navbar display_pay_page display_photos_page display_searchbar display_signup_page display_stats_page display_theme_names display_theme_names_asDropdown display_titlebar display_todays_birthdays display_user_card display_user_card_mini display_user_list display_admin_page display_admin_ustats_editor display_admin_uphotos_editor display_admin_uflags_editor display_admin_umsgs_editor display_years_forDropdowns display_users_forDropdowns display_config_forDropdowns display_zodiac_icon display_debug_one display_debug_many display_debug_code display_debug_large get_config_forDropdowns :debug ); %EXPORT_TAGS = ( debug => [qw(display_debug_one display_debug_many disp +lay_debug_code display_debug_large _tests)], ); ########################

      Cycles in use statements can cause issues. Often hard-to-diagnose problems.

      Breaking the cycle by making one of them a just-in-time require instead of a use is often a good solution.

      # AAA.pm package AAA; use base 'Exporter'; our @EXPORT = qw(aaa); use BBB qw(bbb); sub aaa { my $arg = shift; return 0 if $arg <= 0; return 1 + bbb($arg - 1); } 1; # BBB.pm package BBB; use base 'Exporter'; our @EXPORT = qw(bbb); # use AAA qw(aaa); sub bbb { my $arg = shift; return 0 if $arg <= 0; require AAA; return 1 + AAA::aaa($arg - 1); } 1; # main.pl use AAA; use BBB; print aaa(3) + bbb(4), "\n";
