Values can range from approximately 2.226 x 10 -308 to 1.797 x 10 308.SAS uses fixed length character strings. So the TRIM () function will trim the trailing spaces from the value of a variable, but as soon as you put it back into a variable SAS will pad it with spaces to fill the length of the variable. What do you want to use the TRIM () function to do?Normal SAS syntax does not generate empty string, so just because you did not type the space between the quotes you still gave tranwrd a string with one space to replace the string with one period. If you want to replace a string with nothing you will need to use TRANSTRN() function. To actually create an empty string instead of the string with ...The KSTRIP function returns the argument with all leading and trailing SBCS blanks removed. If the argument is blank, KSTRIP returns a string with a length of zero. Assigning the results of KSTRIP to a variable does not affect the length of the receiving variable.
