+ 20 zero terminated help-string
This message is sent by an application in reply to a HelpRequest message.
Max length = 256-20-1 = 235 chars. Escape codes may be used under RISC OS 3 !Help or equivalent.
The current !Help implementation passes the message block direct to OS_GSTrans before checking for "\" escape codes - hence passing CR or LF terminated strings and using "|" codes other than |M is undocumented.
See PRM 3, page 245.
