Bash syntax variable value assignment

I am new to bash scripting. I came across the following piece of code and I am not able to figure it out. Please help me understand.

var1=$var1 some_function_call $var2

var2 is argument to "some_function_call" function.

I am not able to figure out exactly what is going on here. Thanks in advance.

Also any pointer to good bash scripting tutorials would be nice.

Thanks.

The environment of the new some_function_call process has "var1" set to the value of $var1; the environment variable does not change in the main interpreter. The value in $var2 is passed as an argument to some_function_call.
