Visustin generates flow charts from Rexx source code. REXX stands for REstructured eXtended eXecutor.
The support is based on TSO/E REXX Reference (for z/OS v1R8 and z/OS.e v1R8 from 2006). Visustin works with other Rexx code as well.
Visustin is not fully compatible with ooRexx or NetRexx.
Visustin supports the following Rexx statements.
| Statement type | Statement |
|---|---|
| Conditional statements | IF..THEN..ELSE |
| Multiway decision | SELECT..WHEN..THEN..OTHERWISE..END |
| Looping | DO..END |
| Loop exit and continue | ITERATE, LEAVE |
| Jump | SIGNAL |
| Return | RETURN |
| End program | EXIT |
| Line numbers and labels | MyLine: |
| Comments | /* Comment */ |
Most other statements are handled as regular statements.
The following statements are unsupported. Unsupported means you see the code in the graph as a normal statement, not as a branch or a jump.
