I am trying to write a macro creting automatically a certain number of saveboxes. Therefore I would like to use the concatination of the value of a string and a counter to name the saveboxes. I tried the following and latex complains "Missing Contorl sequence inserted" every time I try to use it.

    The main problem with your use of \newsavebox is that it requires a control sequence rather than just a string. Hence the use of \csname ...\endcsname to construct the control sequence. – Werner Jul 31 '13 at 20:32
  • @Werner: I noticed that for newsavebox it works if I add the backslash ``, however I have issues with actually using the box later. – ted Jul 31 '13 at 20:36

This will create saveboxes \MyStringa to \MyStringz:

  \expandafter\newsavebox\csname MyString\@alph\count@\endcsname
  • why are you using \count@ instead of newcounter? Also any idea why I am seeing errors for \newcommand{\floatRow@resetList}? – ted Jul 31 '13 at 20:29
  • @ted: Is \floatRow@resetList already defined? – Werner Jul 31 '13 at 20:30
  • @Werner: no. I have no idea how to write a package but thought I found something I could work on, and wanted a namespace of my own, e.g. \floatRow@ (I think i should go for something else due to the package of that name), but for simplicity I started with just one tex file, so it is in my main document. – ted Jul 31 '13 at 20:34
  • @egreg: I did some research, you use a tex counter, while this article explained the reasons, I do not understand what @ translates to since count expects a number after all I know. WOuld you enlighten me on its meaning in the conjunction with count? – ted Jul 31 '13 at 21:00
  • @ is just part of the counter name that @egreg is using. In the context of \makeatletter the @ is treated just like any other letter of the alphabet – A.Ellett Jul 31 '13 at 21:15
