Ok, so you don't need overlays or any of that
funny stuff.? Are there 
 any macros in there?? You could just use the paper tape tools (pal11 
 and link11) to do the job.? Or the assembler and linker in DOS-11.
 Alternatively, there's an assembler and linker that runs on Linux, I 
 forgot who wrote it, it was mentioned not too long ago.
 In any case, this would be a trivial link, so converting the resulting 
 executable image file to an equivalent LDA file would be easy enough.

 ? There are three MACRO-11 source files that have to be separately 
 assembled and then linked into an absolute memory image.

 I don't remember the format of a task file, but object files in RSX 
 and RT11 are nearly identical.? 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.? Converting 
 that to handle task files is likely to be pretty easy.
