Unlike PL1PL/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.
Line 30:
<br>
Compilers were available for a number of microprocessors including the 8080 Z80.

Kildall's original PL/M compiler was implemented entirely in standard Fortran 66.
