bad argument stringp nil

[Anonymous]

Hello,

I have a custom lisp routine LAYMOVE.LSP that works in conjunction with a custom screenmenu LDF.MNU (as well as ldf.mnr, ldf.mnc, ldf.mns)

The routine is working fine on two of three workstations.  The intention of routine is to move selected drawing entities from one or more single-node layers to a three-node layer system.   (i.e.  item selected on layer, i.e.,  "arwall" can be moved to layer "1st-flr-arwall").

The error  "bad argument: stringp nil" is received.  I try performing same exact function on other stations in same drawing using ACA2014 and no error received.

Is it possible that there is a setting or configuration on problem pc that is different from others?

thank you,

Edward

Welcome to the Autodesk Community, Edward

At the workstation where the code is giving error, try this:

in vlisp editor (VLIDE), menu debug and break on error,

then load your code, run the code and when an error occurs,

go to menu debug and last break source, to see what is causing the error, and the error should be highlighted...

The "bad argument: stringp nil" error, means that a function is waiting for a string argument, and received a nil as argument.

Further to Henrique's suggestion, here is a tutorial explaining the debugging process to help you locate the error.

I tried steps but must be missing something... any chance the instructions can be itemized (bullet listed?)

thanks kindly,

another point to add..

The routine works on two other workstations with same cad software and version.

Is there some possible setting variable I am missing?

Where do you get stuck when following my tutorial?

I found solution to my "error: bad argument stringp nil" :

I have the lisp routine on a network server (that is in trusted file location) but tried adding a options>file support path>    pointing to that same directory and voila, the lisp routine then finds the LDF.MNU  file it is seeking for list of choices and routine works as should be.   The lisp code is fine, and ultimately just a network path issue.

thanks to all
