Description

Dear gams team,

I realized that a $load of a parameter with $gdxIn in which acronyms are
used will fail when the acronym is defined after a definition of a set.
As a workaround I defined all acronyms at the top of each program, but
this is rather upsetting.
The small example below demonstrates the strange behavior. Maybe I
missed something in the documentation? Hope to hear from you soon.
