x[n_] := x[n] = Is ok. This is a construction known as memoization.

@vsht I suggest you contact support@wolfram.com about this.

comment How to code a For-loop within Interval correctly?
Could you clarify "look through these real values in the interval" a bit more? myint1[[1]] contains two values and it seems you want to step from the minimum value to the maximum value, but what is supposed to happen with the spXX lists then? Those lists are much longer than the two steps that j could take. Do you want to look for the nearest value to j or so? Or do you want to select only values in the spXX arrays that lie in the interval given by myint1[[1]]? In that case you could use Select. But please, be clearer about your intentions. We're not mind readers.

8 is fine, but 9.0.1 and 10.0.2 never seems to stop. Also Windows (8.1)

comment Difficulty with Manipulate that has same variables as other code lines in a notebook
Put the Module outside of the manipulate (let it surround it). Better yet, use DynamicModule instead.

comment How to code a For-loop within Interval correctly?
Welcome to Mathematica.SE! Perhaps you should explain a bit better what you're trying to do. A For loop is usually not the best way to solve things in Mathematica. Your combination with Reap and Sow suggests that Table might be better suited here. Anyway, you get an error in the second part because you use j as an index in a list, with j not containing an integer. j = Min[myint1[[1]]] picks the smallest (real!) value in myint1[[1]].

You might be interested in MaTeX which seems to be able to do similar things, but looks simpler.

comment FilePrint doesn't print file when running on Wolfram Programming Cloud
Please provide a more detailed, but simple, example of what you did. This might be an issue with file paths and directories that are treated differently in the cloud than on the desktop.

comment Mathpsfrag: failed setup at MathPSfragConfigurationTest (UnPSfrag) line (Windows 8)
Could you link to the documentation of mathpsfrag or MathPSfragConfigurationTest? I can't find it in the built-in documentation. Are you using some kind of external party package?
