APL for the MCM/70 was Microcomputer Computer Machines's APL\360 clone, with a few exceptions,[1] most significantly Scan performing reduces over suffixes instead of prefixes. This was due to a misunderstanding, but had to be perpetuated due to the user base.[2]

Internal types

According to page 220 in the user manual[3], the data types available are as follows:

  • 1-byte characters
  • 1-byte integer
  • 2-byte integer
  • 4-byte integer
  • 8-byte integer (?)
  • 8-byte (double precision) floats (?)
