This modification of the PAL III Assembler speeds up assembly

on the ASR-33/35 and operates only with this I/O device.

Operation is essentially the same as PAL III, except that an

additional pass has been added, Pass 0. This pass, started in

the usual manner, but with the switches set to zero, reads the

symbolic tape into a core buffer area. Subsequent passes

then read the tape image from storage instead of from the

Teletype.
