I have a utility script that runs a "proc summary" on a specified dataset and a variable or list of variables (I'll put it at the end). It runs directly in a Unix directory and I deliberately do not assign any user formats because I want to look at the raw values. However, when the summary runs I want it to honor the normal sas numeric formats like DATE7. This works mainly very well but sometimes there is a user format assigned to a numeric variable that is something like vtpcd. but the trouble is the raw numeric value will have a decimal place but the user format does not show these decimal places. Here is an actual example of the script run on a dataset in a directory.

$ summary 'vtpcd vtp' vit Obs VTPCD VTP _FREQ_


But the problem is that the VTPCD numeric variable has the format VTPCD. assigned and so when this utility runs it does not know to state the numeric values to one decimal place. The last two values should be "2.1" and "2.2" and not both "2". But if I cancel the numeric formats with "format _numeric_;" in the "proc summary" step then I will lose it for normal numeric formats such as DATE7. as well, since ths is a utility that could be run on any dataset and any list of variables.

Is there a simple way round this? Ideally there would be a default format I could specify where a user-defined numeric format is not found.

Here is the script I am using, for what it is worth.

#!/bin/bash # Script : summary # Version : 1.0 # Author : Roland Rashleigh-Berry # Date : 23-Aug-2004 # Purpose : To run "proc summary" on a dataset and display the output data set # (uses SAS). # SubScripts : none # Notes : SAS dataset file name extension .sas7bdat will be ignored. You # can subset the output dataset. See usage notes. # Usage : summary sex acct # summary 'sex agesub' acct # summary 'sex agesub' 'acct(where=(fascd=1))' # summary 'sex agesub' 'acct(where=(fascd=1))' 'where _freq_>20' #================================================================================ # PARAMETERS: #-pos- -------------------------------description-------------------------------- # 1 Variable(s) to summarise. If more than one then enclose in single quotes # and separate with spaces. See usage notes. # 2 Input dataset. Too add a "where" clause put in quotes.

dset=$(echo $2 | sed 's%\.sas7bdat$%%')
