The difference is that the RT11 ones are "formatted binary", the same structure as abs loader data, where records start with a byte of 1 followed by a byte of 0, then load address and length (or the other way around). RSX uses RMS variable length records instead, so you get a record containing a load address and data, but the length is handled by RMS. The conversion between the two is pretty trivial. >>> >>> PIP on RSTS can do this, for example RSX to RT11 would be "pip foo.lda/fb=foo.obj". >>> >>> I have somewhere a Python script that turns an a.out format executable (from the GNU linker) into an abs loader file.

I don?t have RT11 at the moment; I have the RSX AME on VMS.
