Also, the changes in current CVS are summarized as follows: - Fix for ADF-GLS test with missing values - Fix for detection of unit-diagonal matrix (oops!) - Add $fcast and $fcerr accessors for use with fcasterr - Autocorrelation test: use Kiviet's original 1986 formula for the LMF statistic - system command: enable naming of systems in the manner "sysname <- system" - system command: several other changes (write this up when done) - remove obsolete commands: fit, multiply - consolidate the commands corc, hilu and pwe into one new command with options: ar1 - merge with fcasterr command with fcast - Fix for the case of graphing 6 time series together - Fix bugs 1908139, 1909469 - Fix documentation of $stopwatch - Move handling of strings into "genr" - Fix sub-sampling bug (which was new in 1.7.3) The changes to commands mentioned above (ar1, fcast) should mostly be user-invisible: I've kept the old forms (e.g. "corc", "fcasterr") as aliases for the present. The exception is "multiply", which struck me as very ad hoc and which is gone altogether. The new handling of string variables may require changes to some scripts but it's definitely an improvement. You now use the "@varname" form of a string variable (with '@' prepended) only where the variable should be treated as a macro -- that is, the value of the variable should be dumped directly into the command line before execution. Otherwise you give the plain name of the variable. Example script: open data4-1 string s1 = "test" # make a copy of s1: string s2 = s1 # use s1 in printf: printf "s1 = '%s'\n", s1 # use s1 as a macro: series @s1 = sqft^2 # print the value of s1: print "@s1" # but more easily... s1 # length of s1 printf "s1 is %d characters\n", strlen(s1) Allin.
