David,

If necessary, compute and save your z-scores using the DESCRIPTIVES
command. If you already have saved your variables as z-scores (e.g.,
ZVAR1 to ZVAR10) you can transform them to 0-100 using the CDF.NORMAL
cumulative distribution function (listed under the COMPUTE command --
the short form is CDFNORM), as follows:

GET FILE = "C:\Data.sav".
DESCRIPTIVES VARIABLES = VAR1 TO VAR10 /SAVE.
DO REPEAT K = ZVAR1 TO ZVAR10.
COMPUTE K = 100*CDFNORM(K).
END REPEAT.
SAVE OUTFILE = "C:\Data.sav".

I have a z-score (ranges from -2.7 to +2.4) that I would like to
transform to a 0 to 100 point scale (same distribution, just different
metric).  Any suggestions would be appreciated.

Thanks in advance.
