	your example is correct. the reason it does'nt work from Turbo C 
is that Turbo C passed the arguements in registers by default, while
gulam is expecting them to be on the stack (like the normal C stack
frame conventions). (is there a option in TC to do this??)

	on a related note: the correct way to check Gulam's magic
number is to get the long at addr (*shell_p - 10), mask out the upper nibble
of the long with 0x00FFFFFFL, and compare the value against
0x00420135L. The reason for this discrepancy is that there seem to be
two flavors of gulam: one with magic # 0x86420135L and one with 0x00420135L.
This way should be a little more reliable than testing just the second
half of the magic number by testing the short value at addr (*shell_p - 8).

hope that helps,
