How to save an optimization model and re-solve it later

[GabrielYin]

Hi GAMS experts,

I'm curious if there is a way to save the GAMS-generated model into a file, and then I could re-solve the saved model in another process of GAMS. I'm using GAMS/CPLEX and it could allow me to save an LP file, but I don't know how to convert that LP file into a GAMS readable model format so I don't need to redefine model variables/equations etc. again.

Any help would be appreciated! Thanks in advance.

Best,
Gabriel
