How do you remove leading spaces from a macro variable in SAS?
To trim macro variables %trim and %left function can be used to remove trailing and leading space. But In general, while the macro variable is created it does’nt store leading or trailing space in it .
How do you remove spaces from a variable in SAS?
set string; comp = compress(text, ”, ‘a’); run; In addition to the blank space specified in the second parameter, the ‘a’ modifier in the third parameter tells SAS to remove all of the alphabetic characters from the text.
How do you delete blanks in SAS?
Remove Leading and Trailing Blanks with the STRIP Function One of the most used functions in SAS to remove blanks is the STRIP-function. Like the TRIM- and TRIMN-functions, the STRIP-function removes trailing blanks. However, the STRIP-function also removes the leading blanks from a string.
How do you resolve a macro variable in SAS?
You can use these references anywhere in a SAS program. To resolve a macro variable reference that occurs within a literal string, enclose the string in double quotation marks. Macro variable references that are enclosed in single quotation marks are not resolved.
How do you remove leading spaces in SAS?
- STRIP function – removes all leading and trailing blanks. STRIP Function in SAS Removes all the leading and Trailing spaces.
- TRIM function – removes all trailing blanks. TRIM Function in SAS Removes all the Trailing spaces.
- COMPRESS function – removes all the spaces or blanks.
What does Strip do in SAS?
The STRIP function returns the argument with all leading and trailing blanks removed. Assigning the results of STRIP to a variable does not affect the length of the receiving variable. If the value that is trimmed is shorter than the length of the receiving variable, SAS pads the value with new trailing blanks.
How do you delete a record in SAS?
To remove observations in SAS, you can use the IF statement in a DATA step. Suppose you want to exclude all observations whose scores are greater than 100.
What is Mprint in SAS?
The MPRINT option displays the text generated by macro execution. Each SAS statement begins a new line. Each line of MPRINT output is identified with the prefix MPRINT( macro-name):, to identify the macro that generates the statement. Tokens that are separated by multiple spaces are printed with one intervening space.
How do you remove leading and trailing zeros in SAS?
Re: remove leading and trailing zeros from numeric data ‘ mult=10) 0 – < 1 = ‘9’ (prefix=’. ‘ mult=10) other = [17.1] ; run; Make sure to round the values first. Use the -L modifier on the format specification if you want the leading spaces removed.
Which function removes Allleading and trailing Whitespaces Instring?
The STRIP function is similar to the TRIM function. It removes both the leading and trailing spaces from a character string.
How to remove leading blanks from a string in SAS?
One of the most used functions in SAS to remove blanks is the STRIP-function. Like the TRIM- and TRIMN-functions, the STRIP-function removes trailing blanks. However, the STRIP-function also removes the leading blanks from a string. If the string consists only of blanks, then STRIP-function returns a string of zero blanks.
Why are there leading blanks and trailing blanks in my macro variables?
Note that you get leading blanks if the origin is a numeric variable and trailing blanks if it is a character variable. Here is a bit of code you can try to explore the different ways of creating macro variables with or without blanks.
How can I make a macro variable with a trailing space?
First let’s make some macro variables that contain trailing spaces. Note that it is actually hard to make macro variables that actually contain trailing spaces, unless you use SAS code, and even then you need to use poor coding techniques. Like using the older CALL SYMPUT () function instead of the newer CALL SYMPUTX () function.
Is it possible to trim a value in a macro variable?
It does not apply to queries that pull just one value. Before they created the TRIMMED keyword the trick to get SQL to trim a value placed in a macro variable was to use the SEPARATED BY keyword even when the query could only produce one observation. you can see there is space between output and (,). how to remove that?
