My executable, compiled by Turbo C for dos16 has very large sizes.

So I'm looking for the way of some dynamic linkers or loaders of library.

I've read LoadLibrary() API for dos32 (Causeway extender) at Openwatcom C.

Any idea for dynamic linker or loader of library for dos16 like DLL for Windows?

Related to FASM ??? What's in ??? Maybe some optimization would be needed. Idea

There used to be "overlay technology" ... but I would NOT recommend it at all Sad

Maybe true, but it's DOS32, NOT DOS16.

For DOS32 you can use HX and LoadLibrary in Win32 style (maybe better than the OS/2 style supported by Causeway).

For DOS16, see above Sad

TurboPascal has a smartlinker built in, so do other Pascals, so they can produce smaller binaries than C. TP even supports overlays, but I agree it's probably easier to just UPX the binary.

.DLLs? Untested but take a look at this:

DLL - Andys Dynamic Link Library routines.
Is a code module which provides support for dynamic linking to librarys and routines whose names are determined at run time (rather than compile time), in a largely platform independant way.
