I have just tried to run RPSORT.COM on my W7 64-bit machine and had an error message to say that the software will not run on a 64-bit machine. To be honest, this is a major disaster for me since all of the 22 years archive data repy upon using this as the sort programme.
An extract from one of the pure text data files that I am using is:
1 06284U 72069D 12165.73374331 .00001320 00000-0 28012-3 0
Characters 3-7 are the five-digit catalogue number and 19-32 are the date (YYddd.dddddddd).
The RPSORT command is run as part of a large batch file and it looks like (one line command for each file to be sorted):
RPSORT CISPRSAT.DAT /+3:5 /+19:14 CISPRSAT.SRT
Where CISPRSAT.DAT is the input file (to be sorted), /+3:5 defines the primary sort field start point and number of characters, /+19:14 defines the secondary sort field in the same way and CISPRSAT.SRT is the output file (sorted file).
Of course, other software will look different, but it gives an idea.
Any assistance in finding a replacement would be appreciated please - I admit that I cannot find anything obvious. Many thanks in advance.
