PDE-PER001 Internal error (depep 2).

Question

PDE-PER001 Internal error (depep 2).
What is this? This error comes while compiling forms designed in Form 6i.
And form is not compiled due to this.
I have seen this error first time.
Please suggest me.
Regards,

There are a lot of things that you do to try and fix strange errors like these.
1) NOT FORWARD COMPATIBLE
I think I have seen this error when you save a file in a newer version (Forms 9)
and then try and open it in an older version (Forms 6) - rather than the other way round
that you are describing.
Please provide the two versions of forms that you are dealing with.
2) TOO MANY FILES OPEN
This error can occur when you have too many files open in Forms Builder at once.
Does the problem occur when you only have one file open ?
Does the problem occur when you have started Forms Builder, then opened a single file ?
3) LOG OFF / ON
Strange errors like this can often be fixed by logging off, then close the file, then open it,
then logon, then do a compile all code (CTRL SHIFT K), then save.
After that you can do a compile (CTRL T) to create the runtime FMX
4) COMPILING
Files can be dependent on other files, so make sure you
Upgrade and Compile the files in the following order.
* PLL Libraries
open each library
Make sure you do this in the correct order.
the highest level libraries first as libraries can be attached to other libraries.
do a full compile (SHIFT CTRL K)
then an incremental compile (CTRL K)
- this second compile often fixed problems in the past, probably not needed now but worth a try
save.
* Referenced forms *.FMB and object libraries *.OLB
To upgrade these open each one, then save
You dont need to compile these.
* The actual form
disconnect, open file, connect, full compile code (CTRL SHIFT K), generate FMX (CTRL T), save, close, open
5) CONVERT TO TEXT, THEN BACK TO BINARY
File corruption problems can often be fixed by converting the file to a text file, then back to binary. In Forms 6 use "File -> Administration -> Convert" Forms 9 and 10 use "File -> Convert". Convert Forms from FMB to FMT and back to FMB again. For libraries use PLL > PLD > PLL. Object Libraries Same OLD > OLT > OLB. Also do the same for any referenced forms.
