This could be a totally stupid question, but I'm trying to do this blind. Is there a way to get a list if environment variables defined at run time? There is a get and set, but I don't know the name of the variable I need, so I want to get a list. This should work cross platform, I think.

Stupid question on my side just to check whether I've understood you correctly: *are* you blind?

Regarding your problem: use GetEnvironmentVariableCount and GetEnvironmentString from unit SysUtils.

Getting the list of environment strings, i.e. name=value pairs:

  SysVarCount:=GetEnvironmentVariableCount;
  for i:=0 to SysVarCount-1 do begin
    Variable:=GetEnvironmentStringUTF8(i+1);
  end;

Get a specific value:

Value:=GetEnvironmentVariableUTF8(VariableName);

The UTF8 functions are defined in lazutf8, others are in SysUtils.

I knew there was something for what I needed. Thank you, and no, not blind except maybe selectively.

I was confused by your "but I'm trying to do this blind". As we already had some questions from really blind people I wanted to be sure :) (that's also why I top posted, because blind people normally use screen readers which would repeat the quote again if I'd do an inline posting...)
