call GAMS from GAMS : GDX file exchange
call GAMS from GAMS : GDX file exchange
Dear GAMS users,
I am trying to call gams file from gams. I have tried to follow the example given in link below,
https://www.gams.com/help/index.jsp?top ... m_gams.htm
I have removed invert1.exe contribution and make it quite simplified. Now main aim is to create a GDX file in one file (invert,gms) and pass its values to another file (invert2.gms) which will further create another GDX file (mygdx1.gdx) with new parameter and call it in first (invert.gms) file. While running the program invert.gms, it is unable to read mygdx1.gdx i.e. program invert2.gms is not being executed from main file. PLEASE HELP !!!
Note: Please find attached gms files, both of them are kept in same directory.

RE: call GAMS from GAMS : GDX file exchange
Hi Mittal
In this case, you have to use the “compile time†version of the gdx command:
$gdxout 'mygdx.gdx'
$unload i
Using the “execute†version means that this command is done during execution time meaning that during compilation time the file mygdx.gdx isn’t generated and not available in the call of invert2.gms (if you run the two files separately, it works because in that case, the file is generated.

Re: call GAMS from GAMS : GDX file exchange
Dear Renger,
Thanks for your reply but still am unable to execute invert2 from invert.gms. I would really appreciate if you can modify the code or else provide me any source or link. One more thing I want to clarify I want to run single file invert.gms and exceute or call invert2,gms in between.
Thank you

If I change the invert.gms to (note that you forget to close the table by a semicolon) the following, it runs fine on my computer:
set i /i1*i4 /;
$gdxout 'mygdx.gdx'
$unload i
alias(i,j);
table a(i,i)

Re: call GAMS from GAMS : GDX file exchange
here some things you could try:
check if it runs in a dos window. open one and type gams invert.gms.
did you add the second file to your project?
run the first file without the call of the second file.

RE: call GAMS from GAMS : GDX file exchange
Move the files to a directory with a simpler name (not so many empty spaces) and try again.
Did you add the changes I sent you?
If you comment the “call gams invert2…†line out does invert.gms produce a gdx file?

Re: call GAMS from GAMS : GDX file exchange
Dear Renger,
Yes I have Incorporated the changes you have told into invert.gms, further commenting the invert2.gms call, invert.gms is producing gdx file.
Moreover, I have moved the files to simple directory. E:\GAMS
Still I am getting the same error :
GDXopenReadfailed: E:\GAMS\mygdx1.gdx
MSG: No such file or directory
Is there any such settings I should do in GAMS ?? Or should I reinstall GAMS.

Did you add the changes I sent you?
If you comment the “call gams invert2…†line out does invert.gms produce a gdx file?
Cheers

Dear Renger,
while running one invert.gms in DOS I am getting these errors ( I am attaching a screenshot ).
Yes I have included both the files in project Is there a way to check this out ??

here some things you could try:
check if it runs in a dos window. open one and type gams invert.gms.
did you add the second file to your project?
run the first file without the call of the second file.

Dear Renger,
Thanks for your reply but still am unable to execute invert2 from invert.gms. I would really appreciate if you can modify the code or else provide me any source or link. One more thing I want to clarify I want to run single file invert.gms and exceute or call invert2,gms in between.
Thank you

Hi Mittal
In this case, you have to use the “compile time†version of the gdx command:
$gdxout 'mygdx.gdx'
$unload i
Using the “execute†version means that this command is done during execution time meaning that during compilation time the file mygdx.gdx isn’t generated and not available in the call of invert2.gms (if you run the two files separately, it works because in that case, the file is generated.

Subject: call GAMS from GAMS : GDX file exchange
Dear GAMS users,
I am trying to call gams file from gams. I have tried to follow the example given in link below,
https://www.gams.com/help/index.jsp?top ... m_gams.htm
I have removed invert1.exe contribution and make it quite simplified. Now main aim is to create a GDX file in one file (invert,gms) and pass its values to another file (invert2.gms) which will further create another GDX file (mygdx1.gdx) with new parameter and call it in first (invert.gms) file. While running the program invert.gms, it is unable to read mygdx1.gdx i.e. program invert2.gms is not being executed from main file. PLEASE HELP !!!
Note: Please find attached gms files, both of them are kept in same directory.

RE: call GAMS from GAMS : GDX file exchange
YOu’re right. This doesn’t work. But can you try to explain again in more detail what you want to do and why it is necessary to do a call of gams (you could just include the invert2.gms:
*Matrix inversion through passed put and loaded GDX file
*Illustrates GAMS call to GAMS
set i /i1*i4 /;
alias(i,j);
table a(i,i)
i1 i2 i3 i4
i1 2 0 2 1
i2 0 1 1 1
i3 0 0 1 3
i4 1 0 0 1
;
$include invert2.gms
execute_load 'mygdx1.gdx', ainv;
display ainv;
and invert2:
parameter ainv(i,j);
ainv(i,j) = uniform(0,1);
display ainv;
execute_unload 'mygdx1.gdx', ainv;
