PL/I Prime Checker — Pli Code
Checks if numbers are prime.
DECLARE nums FIXED BINARY(31) DIM(3) INIT(7,10,13);
DECLARE n,i FIXED BINARY(31);
DECLARE isPrime BIT(1);
DO n = 1 TO 3;
isPrime = '1'B;
DO i = 2 TO nums(n)-1;
IF nums(n) MOD i = 0 THEN isPrime = '0'B;
END;
IF isPrime = '1'B THEN PUT SKIP LIST(nums(n), 'is Prime')
ELSE PUT SKIP LIST(nums(n), 'is Not Prime');

PLI (Programming Language One) is a procedural, compiled language designed for business and systems programming, particularly for large-scale data processing and legacy IBM mainframe environments.
Primary Use Cases
- ▸Large-scale batch processing
- ▸Business and financial systems
- ▸Mainframe application maintenance
- ▸Data processing for enterprises
- ▸Legacy system integration and updates
Notable Features
- ▸Structured programming constructs
- ▸Strong support for record and array data types
- ▸Compiled for IBM mainframes
- ▸Integrated input/output for batch processing
- ▸Efficient memory and file handling
Origin & Creator
Developed by IBM in the 1960s, primarily as a high-level language for business and systems applications on mainframe computers.
Industrial Note
PLI remains in use in legacy IBM mainframe environments for maintaining mission-critical financial and administrative systems.
