Rexx flow charts

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.

Most other statements are handled as regular statements.
