Help with MF2T file

Hi (first post)
I have converted a few midi files to text using MF2T and back again (after editing) using T2MF.
I recognize the "note on" commands and the "change program" commands but what does a line like "24 Par ch=1 c=1 v=0" mean?
Ideally there is some documentaion for MF2T that would answer this and other questions. (?)
Thanks in advance.
Doug

There is a readme.txt in the mft.zip that explains the various text formatting. For your benefit, I will reproduce the relevant part here:
Format of the textfile:
-----------------------
The following representation of the midievents is generated (between
[] the form when -v is used:
File header: Mfile <format> <ntrks> <division>
Start of track: MTrk
End of track: TrkEnd
Note On: On <ch> <note> <vol>
Note Off: Off <ch> <note> <vol>
Poly Pressure: PoPr[PolyPr] <ch> <note> <val>
Channel Pressure: ChPr[ChanPr] <ch> <val>
Controller parameter: Par[Param] <ch> <con> <val>
Pitch bend: Pb <ch> <val>
Program change: PrCh[ProgCh] <ch> <prog>
Sysex message: SysEx <hex>
Arbutrary midi bytes: Arb <hex>
Sequence nr: Seqnr <num>
Key signature: KeySig <num> <manor>
Tempo: Tempo <num>
Time signature: TimeSig <num>/<num> <num> <num>
SMPTE event: SMPTE <num> <num> <num> <num> <num>
Meta text events: Meta <texttype> <string>
Meta end of track: Meta TrkEnd
Sequencer specific: SeqSpec <type> <hex>
Misc meta events: Meta <type> <hex>
The <> have the following meaning:
<ch> ch=<num>
<note> n=<noteval> [note=<noteval>]
<vol> v=<num> [vol=<num>]
<val> v=<num> [val=<num>]
<con> c=<num> [con=<num>]
<prog> p=<num> [prog=<num>]
<manor> minor or major
<noteval> either a <num> or A-G optionally followed by #,
followed by <num> without intermediate spaces.
<texttype> Text Copyright SeqName TrkName InstrName Lyric Marker Cue
or <type>
<type> a hex number of the form 0xab
<hex> a sequence of 2-digit hex numbers (without 0x)
separated by space
<string> a string between double quotes (like "text").
Channel numbers are 1-based, all other numbers are as they appear in
the midifile.
<division> is either a positive number (giving the time resolution in
clicks per quarter note) or a negative number followed by a positive
number (giving SMPTE timing).
<format> <ntrks> <num> are decimal numbers.
The <num> in the Pb is the real value (two midibytes combined)
In Tempo it is a long (32 bits) value. Others are in the interval 0-127
The SysEx sequence contains the leading F0 and the trailing F7.

Hi Jamie,
Thanks for your assistance.
I did eventually figure out that I had the readme.txt file so was able to find the answer, but do appreciate your reply.
