The symbol ";" is not expected.

Question

Good day people….i am new to AIMMS. I want AIMMS to read from a dat file but it keeps giving me the statement “The symbol ";" is not expected.” The content of the dat file is

COMPOSITE TABLE:
G M P R_M R_P
!-------------
10 8 4 10 15 ;

after removing the symbol ; it pops up another error which is ‘The symbol "15 " is not expected.’

after removing 15, it pops up another error which is ‘The symbol "10 " is not expected.”

Is there something i am not getting right on how to structure the contents in dat file. Kindly help please.

Hi Lawrence,

Parameters without an index domain are not supported by the composite table. Please use assignments instead; for instance the following works:

G := 10 ;
M := 8 ;
P := 4 ;
R_M := 10 ;
R_P := 10 ;

A working copy of the project is included.

Hope that helps,

Chris.

Hello Lawrence,I tried to reproduce the behavior you described, but failed; when you open the enclosed project, and press the MEbutton, the data is read in as follows:After pressing the ME button in the enclosed app.May I ask:Does this behavior persist after restarting AIMMS?Which AIMMS version are you using? (I am using AIMMS 4.86.8)If the behavior persists, how are G, M, P, R_M, and R_P declared?With kind regards,Chris.
