Nested If> Loops

I have looked through previous posts and they do not satisfy my question.

The following seems to work just fine, but is it "legal"?

I can't find a reference to nesting IF statgements in this manner and want to be cautious...

Remark>Pare MIT line down to fit 9 chars
If>MITCNTLG=4
Let>Let>MITLN=00090%MITCNT%%SPRFILE%
ELSE
If>MITCNTLG=3
Let>MITLN=000900%MITCNT%%SPRFILE%
Else
If>MITCNTLG=2
Let>MITLN=0009000%MITCNT%%SPRFILE%
ENDIF

I can't satisfy your question either but I hate to use a bunch of if's where there's a logical relationship so maybe something like:

Let>MITCNTLG=6-MITCNTLG
MidStr>9000,1,%MITCNTLG%,begin
Let>MITLN={"000"+%begin%+%MITCNT%+%SPRFILE%}

This script as posted runs without any results so I assigned a value of 4 to MITCNTLG and got an error saying that EndIf was missing.

I think you can nest "IF" statements any old way that suits you but you must have an "ENDIF" for every "IF"

JRL is correct. Your script is invalid as there are not enough EndIfs. Each If must have an Endif.

Perhaps you meant:

Remark>Pare MIT line down to fit 9 chars
If>MITCNTLG=4
Let>MITLN=00090%MITCNT%%SPRFILE%
Else
If>MITCNTLG=3
Let>MITLN=000900%MITCNT%%SPRFILE%
Else
If>MITCNTLG=2
Let>MITLN=0009000%MITCNT%%SPRFILE%
EndIf
EndIf
EndIf

Although this would also work in this case:

Remark>Pare MIT line down to fit 9 chars
If>MITCNTLG=4
Let>MITLN=00090%MITCNT%%SPRFILE%
EndIf
If>MITCNTLG=3
Let>MITLN=000900%MITCNT%%SPRFILE%
EndIf
If>MITCNTLG=2
Let>MITLN=0009000%MITCNT%%SPRFILE%
EndIf

No real need for elses here since if MITCNTLG=4 it can't be 3 or 2, so each bit can be sequential.

Both versions above are valid.

Thanks to all who responded... lots of ideas and guidance.

It is feedback like this that shows the value of these forums, something I wish other mission-critical software would have.

The lack of endifs is a rookie mistake on my part... oops! My trial values did not test all the loops.

Also, I made a typo by duplicating the let command;

Let>Let>MITLN=00090%MITCNT%%SPRFILE%
