ALBIN is a simple method for constructing relocatable binary

formatted programs, using the PAL III Assembler. Allocation

of these programs can be varied in units of one memory page

(128₁₀ registers). When loading an ALBIN program, the

actual absolute addresses of indicated program elements

(e. g., the keypoint of subroutines) are noted down in fixed

program-specified location on page zero. In order to make

a DEC symbolic program suitable for translation into its

relocatable binary equivalent, minor changes are required

which, however, do not influence the length of the program.

Due to its similarity to the standard DEC BIN loader, the

ALBIN loader is also able to read-in normal DEC binary

tapes. ALBIN requires 122₁₀ locations, RIM loader included.

Piling-up in core memory of ALBIN programs stored on con-

ventional or DECtape can be achieved using the same method

with some modifications ..
