Hi Denis,
Usually, the program's complexities will increase as exponential when
decompose complex conditional statement.
----------------------------------------------------------------------------------------------------------------
| Structured Programming Commands | Maximum of Nested Level for VFP | Maximum of Nested Level for VFP Compiler |
----------------------------------------------------------------------------------------------------------------
| IF ... ENDIF | 63 | 143 |
----------------------------------------------------------------------------------------------------------------
| DO CASE ... ENDCASE | 31 | 143 |
----------------------------------------------------------------------------------------------------------------
| DO WHILE ... ENDDO | 63 | 91 |
----------------------------------------------------------------------------------------------------------------
| FOR ... ENDFOR | 63 | 91 |
----------------------------------------------------------------------------------------------------------------
| SCAN ... ENDSCAN | 63 | 91 |
----------------------------------------------------------------------------------------------------------------
| TRY ... ENDTRY | 63 | 91 |
----------------------------------------------------------------------------------------------------------------
As the maximum of nested level for VFP structured programming commands is 63,
some large program may happen "Structure nesting is too deep" error when decompose
complex conditional statement.
best regards.
