MODRES - PLAY MODULE

AX = 8220h
DX:CX -> MODPARM structure (see #02960)

Return:

Format of MODPARM Structure:

Offset  Size    Description     (Table 02960)
00h    WORD    signature 504Dh ("MP" = Modparm)
02h    BYTE    output device (see #02962 at INT 2F/AX=8221h)
03h    WORD    segment of start of main module (pattern) data
05h 31 WORDs   segment of start of sample numbers 1-31
43h    BYTE    pattern at which to start playing (00h to 7Fh)
44h    BYTE    function
00h play from pattern [offset 43h] until end of the song
01h play indicated pattern [offset 43h] only
45h    BYTE    Machine speed
00h 10-12Mhz
01h 12-25Mhz (default)
02h 25Mhz+
03h mix speed 10kHz (fast 8Mhz machines)
04h mix speed 12kHz (10Mhz machines)
05h mix speed 13kHz
06h mix speed 8kHz (test for 8Mhz machines)
46h    BYTE    allow >64k sample playing
80h MOD has samples >64k in it
else all samples in MOD are <64k

Notes: Main module data and all samples must start on segment boundaries.. In version 2.00 (ONLY) this function carries on playing (works in the background)
