If you know PL/M, please write code for some of the tasks not implemented in PL/M.
Designed and implemented in 1973 by Gary Kildall, PL/M (Programming Language for Microcomputers) is (as the name suggests) a language designed for microcomputer software, particularly system software.
It is approximately a very small subset of PL/1 (though not a strict subset).
The following statements from PL/1 (with some changes) were available:
 assignment
 CALL
 DECLARE
 DOEND
 IFTHENELSE
 GOTO
 PROCEDUREEND
 RETURN
Additionally, a HALT statement, interrupt related statements and a number of compiler directive statements existed.
There are no builtin I/O statements  calls to appropriate routines would be made instead.
Unlike PL/1, PL/M keywords are reserved and so cannot be used as identifiers. The Boolean operators are reserved words: AND, OR and NOT instead of the symbols: &, , ¬.
Available datatypes (BYTE, WORD, etc.) reflected the available types of the microprocessors.
The declaration of structures in PL/M does not use levelnumbers, instead a syntax more like C structs is used, e.g.:
DECLARE A STRUCTURE ( B BYTE, C WORD );
declares a structure A with two members, B and C.
PL/M was used in the development of the CP/M operating system and associated applications.
Compilers were available for a number of microprocessors including the 8080/Z80, 8051, 8086, 80186, 80286 and 80386.
The available datatypes varied depending on the processor.
Kildall's original PL/M compiler was implemented entirely in standard Fortran 66.
