This chapter describes the PL/I Extension that is used to process PL/I source code components.
The PL/I Extension™ gives you the ability to apply the powerful application inventory, analysis, and maintenance capabilities of Revolve to your enterprise PL/I systems. It extends Revolve's analysis and implementation features for use by PL/I programmers.
The PL/I Extension introduces a PL/I language parser that identifies individual components of an application system (such as programs and associated include files, variables, literals, job steps, screens, data files and databases) and adds them to the Revolve project database.
Revolve enables programmers to visualize details of the application project, determine where changes must be implemented, automatically trace the impact of those changes across the entire application project, and document and guide the change process.
The following keywords can be listed as BUILTIN and will be recognized as functions for PL/I Impact Analysis:
| ADD | CURSTORE | MIN | SINH |
| ABS | DATAFIELD | MOD | SQRT |
| ACOS | DATE | MULTIPLY | STATUS |
| ADDR | DECIMAL | NULL | STORAGE |
| ALL | DIMENSION | ONCHAR | STRING |
| ALLOCATION | DIVIDE | ONCODE | SUBSTR |
| ANY | EMPTY | ONCOUNT | SUM |
| ASIN | ENQUOTE | ONFILE | TAN |
| ATAN | ERF | ONKEY | TAND |
| ATAND | ERFC | ONLOC | TANH |
| ATANH | EXP | ONSOURCE | TIME |
| BINARY | FLOOR | PARMSET | TRANSLATE |
| BOOL | HBOUND | PLIRETV | TRUNC |
| CEIL | HIGH | POINTER | UNSPEC |
| CHAR | IMAGINARY | POLY | VERIFY |
| COMPILETIME | INDEX | PRECISION | |
| COMPLETION | LBOUND | PROD | |
| COMPLEX | LENGTH | REAL | |
| CONJUGATE | LINENO | REPEAT | |
| COS | LOG | ROUND | |
| COSD | LOG10 | SAMEKEY | |
| COSH | LOG2 | SIGN | |
| COUNT | LOW | SIN | |
| COUNTER | MAX | SIND |
The PL/I Extension component is installed separately from Revolve. It shares the same operating system and microprocessor requirements as Revolve. An additional 2 Mb free hard disk space is needed to load all corresponding files.
The PL/I Extension checks the local registry at start up for the availability of the IBM VisualAge PL/I product. If it is available, the PL/I Extension uses it to provide PL/I compiling, linking, and debugging facilities.
This section shows which Revolve features are supported in the Pl/I language extension.
