plithon

... is a PL/I to Python transpiler, written in Python
Target: anybody who wants learn PL/I, Python and PLY

Installation

Components needed

• Python 3.x needed
• mySql connector for SQL access

How to run

• Tested only under Windows 11
• Simply copy the plithon.py in your (Windows, see also above) directory
• Call the program like this (sample): C:\apps\plithon>python plithon.py
• Select your PL/I input file in the explorer window
• If you want to include SQL statements, store your credentials in the file "c:/temp/creds.txt". I'll make the location of this file later selectable. Content of this file is one record (here as sample): host="localhost", user="root", password="admin", database="sakila"

Following features are installed in version 1.08:

• dcl variable-name <fixed bin(15|31) | char(length)>;
• variable = <arithmetic-expression> | <string-expression>;
• operators in arithmetic_expression: + - * / ( )
• operators in string-expression: builtins: substr index decimal
• if relational-expression then statement else statement;
• select(expression) when(value) statement; other statement; end;
• put skip list(variable | constant);
• exec sql "select sql-select-field" into variable; - only MySQL connection, sample db sakila (sorry, actual are my credentials hardcoded)
• get list(variable-list); - read variables from console per prompt
• one-dimensional arrays are now supported (only integer indexing is possible)
• record i/o simple version (open close read write) works

Planned for version 1.09:

• two-dimensional array handling
• introduce credential file for mySql access
• error corrections
