A variable of which a part is variable

A variable of which a part is variable

I have variables that look something like this:
$INFOMonday
$INFOTuesday
In my Bash script, I would like to use the value of todays variable, so to
say. I extracted the day with:
dayofweek=$(date --date=${dateinfile#?_} "+%A")
What I need help with, is doing the following:
echo $INFO$dayofweek
Is there any way of adding a variable as part of a variables name? For
example, if it's monday, the echo would return the value of $INFOMonday.
