Analyst is a programming language developed in 1968 at the Institute of Cybernetics of the Academy of Sciences of the Ukrainian SSR under the leadership of Academician Viktor Mikhailovich Glushkov . It is a development of the ALMIR-65 language, while maintaining compatibility with it.

A distinctive feature of the language is abstract data types, calculations in arbitrary algebras, and analytical transformations.
It was implemented on MIR-2 machines.
Later, a version of Analyst-74 was developed, implemented on MIR-3 machines.
At the moment, the language ANALYTIC exists in the form of a computer algebra system ANALYTIC-2010, which is being developed jointly by the Institute of Problems of Mathematical Machines and Systems of the National Academy of Sciences of Ukraine and Poltava National Technical University named after Yuriy Kondratyuk.

Alphabet and basic language constructs
The combined alphabet of Russian and Latin uppercase letters is accepted in the ANALYTICS: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z DU
This approach made it possible to use a 45-key keyboard on data preparation and input devices.
Decimal digits: 1 2 3 4 5 6 7 8 9 0
The constants π and e .
Arithmetic operations in order of precedence:
| Act | Sign |
|---|---|
| exponentiation | ↑ |
| multiplication, division | ×, / |
| addition, subtraction | +, - |
Logical conditions: =, ≠, >, ≥, <, ≤.
In complex logical expressions, signs of logical operations can be used: "NOT", "AND", "OR"
| Sign | Act |
|---|---|
| "" | Highlighting Service Words |
| , | separation of list elements (names, numbers, arguments of functions, procedure parameters, array indices) |
| ; | separation of operators or descriptions from each other |
| . | decimal point in number or end of label |
| ⏨ | mantissa and order separator |
| () | brackets of arithmetic and logical expressions, selection of arguments of functions, or combination of operators |
| [] | Index brackets |
| '' | Highlight output text |
The alphabet of the language also contains generally accepted mathematical symbols: ∞ √ ∑ ∏ ∫ d ∂
An exclamation mark (!) May be used in program text.
The following is a list of the main service words of the ANALYTIC. Service words can be abbreviated provided that they are read unambiguously. Service words are not reserved, because they are indicated by quotation marks.
| "Enter" | "TAKE" |
| "Conclusion" | "EXECUTE" |
| "CALCULATE" | "Where" |
| "Schedule" | "Differentiate" |
| "For" | "BEFORE" |
| "If a" | "HEADER" |
| "Values" | “Otherwise” |
| "Integrate" | "End" |
| MASSIV | "Scale" |
| "ON" | Bring |
| "APPLY" | "Space" |
| "Procedure" | "Let be" |
| "Bit depth" | "Stop" |
| "Line" | "Table" |
| "TO" | "Format" |
| "Step" |
