Another way for the first one is to use /play's "help" feature...
The -t switch forces mIRC to look up the specified topic in the file and play all lines under that topic. For example:
/play -thelp1 help.txt
In the help.txt file you would have:
[help1]
line1
line2
line3
[help2]
...
mIRC will play everything after [help1] and stop when it reaches the next topic header or the end of the file.
