Variable length to maximum

This is rather very simple question. However, after lot of research I
still could not find the answer. Can please anyone provide me syntax for setting the variable length to maximum i.e numeric to 40 and string to 255. Right now I have to manually go in width column of variable view and set it to maximum. I have to set it to maximum as when I have wave 2 data to merge, the length should be the same. Thanks in advance. Manmit |

You can do this with the FORMAT statement, i.e.
FORMAT VARNUM (F40.0). FORMAT VARSTRING (A255). best Staffan Lindberg National Institute of Public Health Sweden -----Ursprungligt meddelande----- Från: SPSSX(r) Discussion [mailto:[hidden email]] För Manmit Shrimali Skickat: den 28 juli 2006 14:21 Till: [hidden email] Ämne: Variable length to maximum This is rather very simple question.

Thanks staffan but the problem is that I need to do for all variables. I have 550 numeric variables and 39 string variables. Can I use something like all varnum and all var string etc..

OK!
You can use the TO functions when the variables are consecutively placed (numerical or string) i.e. Format Varnum1 to VarnumX (F40.0). Format Varstring1 to VarstringX (A255). This can be somewhat tedious, if you have every other numerical and every other string. Perhaps it is possible to use a script or something similar. Perhaps some script wizard on the list could help you. best Staffan Lindberg National Institute of Public Health Sweden -----Ursprungligt meddelande----- Från: SPSSX(r) Discussion [mailto:[hidden email]] För Manmit Shrimali Skickat: den 28 juli 2006 14:35 Till: [hidden email] Ämne: Re: Variable length to maximum Thanks staffan but the problem is that I need to do for all variables.

I don't have time to write the python code for you at test it fully,
But I expect it would look something like the following; Might be a good starting point for some else to finish? Begin program. import spss spss.Submit("GET FILE = 'C:/Program Files/SPSS/Employee data.sav'.") varList=[] for i in range(spss.GetVariableCount()): if spss.GetVariableType(i)=='0': varList.append(spss.GetVariableName(i)) if len(varList): spss.Submit("FORMAT " + " ".join(varList) + "(F40.0). " + ".") End program.

Using Python in SPSS 14, you can build lists of variables based on type (e.g., string vs. numeric) and use those lists of variable names in commands -- but you cannot change the defined width of a string variable via syntax. (The ability to change the defined width of a stinng variable in the Data Editor is not directly supported in syntax, although there is a workaround that involves creating new string variables of the desired width and then deleting the old ones).
Are you trying to set the print/write format of the variables, or just the width of the Data Editor columns? For the latter, you would use VARIABLE WIDTH, which doesn't care about data type or format. -----Original Message----- From: SPSSX(r) Discussion [mailto:[hidden email]] On Behalf Of Staffan Lindberg Sent: Friday, July 28, 2006 7:48 AM To: [hidden email] Subject: SV: Variable length to maximum OK!

Hi Manmit,
You could have a look a the web site of Raynald Levesque http://www.spsstools.net. There you can find a macro called "variable type.sps". It does what you want and will run on SPSS 11.0+.

Manmit:
This message deals first with the change in formats, but then jumps to the real issue: your problem is not with formats but with string variable LENGTH, quite a different matter. 1. A HOMESPUN SOLUTION FOR FORMATS I don't have time now to work out a macro for this, and anyway it is perhaps not worth it for a task to be performed only once, but you can do it in a homespun way like this. If you have some way to rapidly recognize by name which variables are strings, you can open the variable information icon in the toolbar (the small vertical ladder with a question mark), select all variables (or all string variables) and click PASTE. This will copy the list of variables into your active syntax window (or a new one if you do not one already open). Then group the variables in two lists, one for numerical and one for string variables, and write the keywords at the front and end of each list, such as: FORMATS str1 str2 str3 str4 str5 ..... str289 (A255). FORMATS num1 num2 num3 num4 .........num 876 (F40.0). 2. THE REAL PROBLEM IS NOT FORMATS: However, from your original question I tend to infer our problem is not with the FORMAT (the visible number of places) in the variables but the internal LENGTH of string variables. To merge files, numerical variables need no adjustment: all are internally held at the maximum precision allowed by SPSS. But string variables should have the same LENGTH. The visible FORMAT is not important: the resulting merged file will show the format of the first file named in the merge list. The length of string variables is determined at their creation, with the STRING command. One possible solution for your problem is to create new string variables with length and copy the old strings into them. Another is going to the data editor variable view and manually change the WIDTH cell of all string variables to 255.

Although you can set the format of a numeric variable to F40, on most operating systems only the first 16 digits are going to mean anything.
