It's a language that originates in the late 60s - so there are some,
"different" ideas than more contemporary languages.
You can ask for sub-string
PL/I has the concept of a "string", which can be a fixed-length
(possibly not known at compile time), or a fixed size with a 4-byte or 2-byte
runtime length prefix, or, depending on the consituents, a NULL (zero-byte)
terminated string.
For "character-like" strings, the constituents can be 1-byt
