-Q: //I have a batch job consisting of a large number of gams models to be  run, each of these requiring cplex. I am running this on my faculty'​s it system, where we share a number of licenses. ​ It varies a lot how many is available, but sometimes none are  available. This answer is returned to gams, which outputs this and terminates. That is very unfortunate for my application and would very much prefer if it waited ​until a license ​became ​available. So my question is, can some flag be set for either cplex or gams, telling gams to keep trying to find a license?//+Q: //I have a batch job consisting of a large number of gams models to be  run, each of these requiring cplex.

 You can program this into your GAMS program. The GAMS/​CPLEX-link returns with a license error in the solver status. If this happens, you could put your model to sleep for x seconds and try again: You can program this into your GAMS program. The GAMS/​CPLEX-link returns with a license error in the solver status.
