I have just purchased Turbo Pascal for my pc compatible. I have written
an assembly language piece of code, assembled it, linked it, and
converted it to a .com file. It runs standalone, however when I
declare it an external in Turbo it does not run properly. I am
trying to access the character font rom in BIOS using es.

What does one have to save in the way of registers to use a data
segment within the assembly language function? If you have
a working example I would greatly appreciate it.

Thanks in advance.
