text of … between … and … extracts that part of a ‘string’ of text between two numeric bounds which represent the position of the start and end characters to be included. (In programming parlance, this is called a ‘substring’.) For example, given the following case fragment:

           01 Jun 03    20 Jun 03    01 Jul 03    23 Aug 03    02 Nov 03
Test1      1234567      1234567      1234567      1234567      7654321  
Test2      abc                       abcd                      bcde    
Test3      diabetic     diabetic     diabetic                      

then the following conditions are true:

text of Test1 between 1 and 4 is “7654”
text of Test2 between 2 and 3 is “cd”
text of most recent Test3 between 1 and 4 is “diab”
