error expected number I don't know what it mean?

[Diana Clavijo]

 Hi, I'm programing a mathematical model of sequencing and assignment, i have many errors and this is one of these.

model1.dat, line 39 (offset 423):

expected number

context:  param  >>> G <<<  : = 10000;

I need help, thanks for answer me.

I don't see anything wrong with this statement.  Most likely the syntax error at this point is the result of something that is wrong earlier in the file, such as a missing semicolon on the previous line.  (If AMPL is interpreting "param G ..." as more data for the previous parameter, then it will try to read "G" as the value corresponding to set member "param" -- hence the "expected number" message.)
