In some hand-me-down tex i inherited, a control sequence is used as a variable, for instance:
defaccessflavorats
it is used to generate postfixes on included tex files (called, i.e., image01_ats) and the like.
I want to use it in a conditional structure, i. e. something like
ifaccessflavor ats
This text is only shown if the Flavor of Access is 'ats'.
fi
I tried a a lot of variations, including various brackets, escape sequences and macros, but i cannot get it to work. Mostly, not even an error message appears. The online examples i found either deal with a more specific IF, like ifodd, ifx, etc., or more (seemingly) complex cases like testing two macros for identity.
Can somebody clear up the usage for me?

I can recommend themultiaudiencepackage which allows you to separate some parts of your text for different "audiences" and provides higher-level switches. As part of this, you can use itsCurrentAudiencevariable to get the audience you are currently writing for (e.g. for file names).

Thank you! Can you explain what is going on? If i understand it correctly, you def-ed atscomparetoken so that the ifx could work on two tokens - is there a reason you packed the whole thing into a command? Also, do you know why one needs the string as an expansion inside a token (for the ifx case it is clear, but why dies if not work?)

@bukwyrm Correct, theifxworks on two tokens, and the comparison is whether the substitution text (one level of expansion) for the two tokens matches or not. The problem with trying to do this withifis thatiffully expands and then compares the first two tokens; thus,ifaccessflavor atsexpands toif atsatsandais compared tot, with the remainingsatsextraneous.

@bukwyrm Correct, the
ifx works on two tokens, and the comparison is whether the substitution text (one level of expansion) for the two tokens matches or not. The problem with trying to do this with if is that if fully expands and then compares the first two tokens; thus, ifaccessflavor ats expands to if atsats and a is compared to t, with the remaining sats extraneous.– Steven B.
