/****************************************************************
* ENTER.C *
Release 7: RBBS 4.1 Edit 02 - Better prompt in entermsg
Release 6: RBBS 4.1 Edit 01 - Fixed edit problem in edit_txt
- Added L command option to edit_txt
- Allow "personal" messages everywhere
- Cannot send to self anymore
Release 5: RBBS 4.1 Edit 00 - Names now one large field
- Inserted PERSONLY in check_to
- Fixed potential problem in save_draft
Release 1: RBBS 4.0 Edit 18
* This file contains the functions:
* entermsg calls check_to, get_subj, get_text, and edit_draft
* check_to prompts for To:, calls checkuser
* get_subj prompts for Subject string
* get_text prompts for up to 24 text lines
* edit_draft command dispatch
* save_draft appends the message to current .MSG file
* edit_sum offers to change the To: and Subject: lines
* edit_txt prompts for line number to change and offers the
line for editting
