How to set %_INIREAD result to variable

[Xeno]

I'm trying to set the result of an INIREAD operation (the entry in an INI file) to a variable, but I just get the return code of the INIREAD operation (0, or -1). How do I set it to a variable?

Here is my code:https://pastebin.com/4i7u1cFR

@INIREAD returns the item's value, unless there is an error -- the file doesn't exist, the section doesn't exist, etc. -- in which case it's supposed to return -1.

@INIWRITE, by contrast, is supposed to return 0 or -1; not the value you've written. If you don't want the 0 or -1 in those variables, then don't use those variables. (I often use a variable RV for "return value", which I can check later if I want to.)

Finally, SET should have one equals sign, with no spaces. (It seems to work as written, but it's always safer to use the documented syntax.)

~\Work> type test.ini
[xyzzy]
foo=123
bar=455

~\Work> set x=%@iniread[".\test.ini",xyzzy,foo]

~\Work> set x
123

~\Work> unset y

~\Work> set y == %@iniread[".\test.ini",xyzzy,foo]

~\Work> set y
y == 123

~\Work> echo %y%
ECHO is OFF

~\Work> echo %[y ]
= 123

SET X == anything
does not set envvar X at all. It sets a variable whose name is X followed by a space.

The first = terminated the name of the envvar (ending in a space) and the second = became the first character of the value.

Whoops -- you're right!

That may look like it works.

v:\> set zzz == foo

v:\> set zzz
zzz == foo

But I'm confident it isn't doing what's intended. Above, the variable name is "zzz " and it's value is "= foo".

v:\> echo %[zzz ]
= foo

Blame Microsoft. This is yet another of the original CMD quirks TCC has to support.
