Source-derived summary

The Parrot assembly language (PASM) is an assembly language for the Parrot virtual machine.

PASM is the lowest level assembly language in the Parrot stack. The Parrot intermediate representation (PIR) is PASM extended to simplify development of compilers.

The hello world program in PASM is simply:

print "Hello world!\n"

end

Although it appears similar to source code in some high-level programming languages, more complex PASM programs will resemble other assembly languages. The main exceptions to this low level programming in PASM are string handling and, as shown above, input and output. Additionally, PASM has automatic garbage collection from the virtual machine, and it does not allow pointer arithmetic.

Parrot assembly language has more instructions than hardware assembly languages, even CISC processors. This is because the marginal cost of creating a new instruction in Parrot is low compared to the marginal cost of doing so in hardware, and the creators of Parrot had no particular goal of minimalism.

Editorial summary

The public source identifies “Parrot assembly language” as assembly language. This brief keeps that definition visible, then builds a research path around Parrot, assembly and language.

Editorial reviewA concise reference frame for defining the subject, testing terminology and identifying the institution closest to the evidence. The current 157-word lead offers orientation but no explicit four-digit date, so chronology should not be assumed. The selected authority fields contribute no independent date. Its value is orientation rather than verdict, with Parrot, assembly and language providing the first useful test.
Editorial analysis

Why this record matters

A short description can identify a subject without explaining its stakes. For “Parrot assembly language”, the useful work is to connect “assembly language” to the records capable of establishing context and consequence.

Evidence profile

Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Jul 29, 2026. The linked authority identifier is Q7139844. None of the 0 selected statements returned an explicit reference.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Use the entry as an orientation point, then follow its citations and revision history. Names, dates and institutional relationships should be checked against the original record.
