There are several additional PL/I features; here are just a few:
1. Dynamically allocated arrays (COBOL's DEPENDING ON is not a case of dynamic alloc; you still need a fixed upper bound)
2. Variable length character strings with a natural concatenation operator
3. Block structure constructs
4. GET DATA and PUT DATA, which let you associate variable names with values on input and output, very nice for free-form input and self-identifying output; input data could be, e.g.:
INT=0.07, PRINC=1234.56, YEARS=10
5. Type declarations for subroutine/function parms[/u] |

PL/I is a combination of COBOL oriented and FORTRAN. COBOL was my native language. After I learned a lot about PL/I in the seventies I decided to chanche from COBOL to PL/I though nowadays COBOL is creeping towards PL/I; but still slowly  Still I think PL/I is more powerfull. |

Sorry, just putting on my normal "I don't understand it" bigot face....Done CDC assembler, FORTRAN, 1130 Assembler, COBOL(s), IBM Assembler, RPG (yech!) and such, I know that each language has its powers and its weaknesses.....
I just couldn't resist.... |
