DATES:

1. Introduction
   • Features in the PL/1 language and the different compiler versions.
   • PL/1 has been used to process data for business entities and as a development language for coding applications specific to certain processors.
2. Creating Data Fields
   • Compile and execute a simple program.
   • Use the PUT statement to display data.
   • Declare datatypes using the PICTURE attribute.
   • Compile and execute the program provided by the instructor.
   • Create a character string variable containing your name and a fixed binary file with age (in years); then 1- Print the two fields using PUT LIST, PUT DATA, and PUT EDIT. 2- Initialize the data items in a supplied table into variables that contain the PICTURE attribute. 3- Browse the results.
3. Compiling and Link-editing on z/OS
   • Review compile, link, and execute JCL.
4. Programming and Expressions
   • Perform mathematical calculations.
   • Write a PL/1 program which determines the area of a triangle: initialize the base and height variables with values.
5. Program Structure
   • Determine the beginning and end of a routine.
   • Code a main procedure with a simple DO group and a procedure with no parameters.
6. Program Statements
   • Code a DO WHILE statement and IF/DO statements.
   • Print out a multiplication table; for example the five table; then print a string of data, one character on a line.
7. Arrays
   • Find the largest and smallest value in an array.
8. I/O: Input/Output
   • Input a Claims file and format Social Security number, numeric values, and dates.
9. Structures
   • Create and use structures.
   • Execute programs with record I/O.
   • Perform character manipulation with the SUBSTR function.
   • Read each record from the Account Receivable Dataset; then 1- Print every record into the Account Receivable Report. 2- Format the date into mm/dd/yy and permit 20 entries on a printed page. 3- Print a grand total of the Invoice amount at the end of the report.
10. Record I/O
    • Read a set of grades and calculate the lowest, highest, and mean grades.1- Use the GET LIST command for reading data. 2- Calculate values using the Assignment statement. 3- Use conditional expressions for determining the highest and lowest value. 4- Perform looping. 5- Read in a list of grades using the GET LIST command; there will be one grade on a line. 6- The last value in the input stream is a -1, which indicates the end of the list.
    • Display each grade using the PUT LIST command.
    • After all the grades are listed, display the number of grades, the lowest grade, the highest grade, and the mean grade.
11. Stream I/O
    • Display a simple histogram.
12. Storage Allocation
    • Allocate, populate, and display the memory dynamically.
13. Conditions
    • Use conditions to perform error checking at run-time.
    • Read in a Division/Dept Table.
    • Use the ERROR and SUBSCRIPTRANGE condition to check for any errors and whether a high bound has been exceeded.
14. Built-in Functions
    • Practice character manipulation on a varying sized string.
    • Code a function which returns the number of characters in a string.
    • Pass data back and forth to a procedure.
    • Code an external subroutine that receives two arguments and passes back a value.
