always come in pairs. All commands enclosed between BeginLoop and EndLoop are
executed in a cycle.
The command BeginLoop has one text parameter “LoopFile”, which contains the name
(with a path, if necessary) of the so-called loop file. The loop file instructs RefFIT on how to
run the cycle. It is a text file, which has the same number of lines, as the desired number of
cycle steps. Each line contains one or more words separated by space. The first word is the first
cycle variable, the second word is the second variable and so forth.
The cycle variables are used to modify text parameters of the commands in the cycle. If a
text parameter contains combination “%1”, then it will be substituted by the first cycle variable.
The combination “%2” is substituted by the second cycle variable etc. For instance, if the first
cycle variable is “250”, then text string “C:\MYDATA\REFL_T%1.DAT” will become
“C:\MYDATA\REFL_T250.DAT”. Such a substitution, for example, in the File parameter of
the LoadDataset command will cause the loading of a different dataset on each cycle step.
