tcl callout error – 3.8 to 5.5

Femina,

It looks like are trying to run the file (xlt_fo_orc.tcl) vs. the actual proc (xlt_fo_orc); make sure the Xlate is referencing the proc name (xlt_fo_orc).  You may also need to re-build/build the tclIndex file as you may have missed a step in the conversion from 3.8 to 5.5.

Femina,

it is always possible mktclindex didn’t work because there was a syntax error in the tcl file.

Although nothing looks wrong in what you listed, I would suggest manually checking that your function exists. That way you can at least narrow down the likely cause to being either in the function itself or your translate file.

to manually check set your site, then go into tcl and try the function from the command line.

If you get an “invalid command name” error then your function isn’t being loaded by mktclindex

If you call it w/ no parameters and the function exists then you should see an error to the effect that some variable doesn’t exist or that your passing the wrong numberof parameters.

$ tcl

tcl>echo $env(HCISITEDIR)

/hci/qdx5.5/integrator/clprod

tcl>qwertyuiop               ;# illustate a non-existent command

Error: invalid command name “qwertyuiop”

tcl>xltConvertDate         ;# this is valid in my system

Error: can’t read “xlateInVals”: no such variable

Greetings,

You may wish to check the tclIndex file in your tclprocs directory for the proc name to verify that the index entry exists and with the correct name.

For example with your proc, an entry like:

set auto_index(xlt_fo_orc)

]

would be there.

I hope that this helps you out.

I noticed something between 3.8 (our production) and 5.5 (our test).  In 5.5, under hcitcl shell, help lassign does not return any help but instead an error, although running the command from the shell works as one would expect.  Under 3.8, help lassign gives you the proper help.  In both 3.8 and 5.5, there is an hci provided extension, called assign_list, which seems to be the same thing as lassign.

Of the code snippets that are not working, do they all contain the lassign command?  Of the ones that are working, are they missing the lassign command?  If you replace lassign with assign_list in the TCL you provided in your example, does it work?  (Remember to reload the TCL proc to your process).

Hope this helps,

Bob

Help was part of the TclX interpreter.  When you ran hcitcl prior to Tcl 8.4 you ran the interpreter in TclX.  TclX was not updated along with 8.4.  Now TclX is a separate libarary and the hcitcl interpreter runs under tclsh.

Also you will note that you no longer can run a script like:

                hcitcl -f

Femina,

That is just one of the reasons we do not use XLTP ‘snippets’ imbedded in an Xlate.

Instead we create a Tcl proc (easier to make it reusable that way as well) and invoke it from the Xlate Action (COPY, CALL, whatever).

That way should we fumble finger the curly braces, square brackets, or any other Tcl sensitive encapsulation, the error we get is inside the module, not inside the Xlate.
