far call in assembly

How can I call a procedure if I know offset and segment?
When I execute

call 1122:3344

TASM complains "Near jump or call to different CS"

I can make a jump like
db 'EAh'
dw Offset
dw Segment

But how to make a call?

CALL CS:OFFSET

is the right syntax.  Are you using a .MODEL directive and specifiying SMALL?

The correct bytes for this would be:

db '9Ah'
dw OFFSET
dw SEGMENT

You might try it this way:

CALL FAR PTR SEG:OFFSET

This is the MS syntax to force a FAR CALL when the current default memory model specifies a NEAR CALL.  It seems to me that TASM is very close in its syntax.
