in the case of the first 3 i want the last 4 chars e the case of the last i want the last 3 chars, how can i get them using substr and get them in the correct order eg: RJ11.

You can do this with regular expression matching using prxchange:

data have;
infile datalines;
input mystr $ @@;
datalines;
DDSPRJ11 DDSPRJ12 DDSPRJ12 DDRJCT
;
run;

data want;
  set have;
  suffix = prxchange('s/(DDSP|DDR)(.*)/$2/', 1, mystr);
run;

How can I get last characters of a string, Since in Javascript a string is a char array, you can access the last Javascript strings have a length property that will tell you the length of the  I got this chars DDSPRJ11 DDSPRJ12 DDSPRJ12 DDRJCT. in the case of the first 3 i want the last 4 chars e the case of the last i want the last 3 chars, how can i get them using substr and get them in the correct order eg: RJ11.

@user667489 is perfect answer if it you have can read all of values separately. if it is in same variable as shown below you can use the same code given by @user667489. and add can add can function. prxnext, can also be used to achieve the same. both examples are shown below

data have;
 val= "DDSPRJ11 DDSPRJ12 DDSPRJ12 DDRJCT";
 run;

/* using prxchange with scan*/
 data want;
set have;
suffix = prxchange('s/(DDSP|DDR)//', -1, val);
 do i = 1 to countw(suffix,' ');
 newstr= scan(suffix, i);
output;
 end;
 drop suffix val;
 run;

/* using prxposn*/

 data want;
length val1 re $200.;
 set have;
start = 1;
stop = length(val);

re = prxparse('/(DDSP|DDR)/');
set have;
call prxnext(re, start, stop, trim(val), position, length);
  do while (position > 0);
     val1 = substr(val, position+length, length);
     call prxnext(re, start, stop, trim(val), position, length);
     output;
  end;
drop re start stop position length val;
run;

in javascript, how can i get the last character in a string, In this case, we need to display only last 4 characters to mask the sensitive data. To get substring having last 4 chars first check the length of string. If string length​  after declaring the string variable just fine the string length using strlen. then take the position of the last character of the string into an integer and using offset you can find whether the character in the desired position is '/' or not. the code is as follows :

Here is how you can do it in a simple python. I assumed that, you want last 4 char of every word except last.

string_1 = 'DDSPRJ11 DDSPRJ12 DDSPRJ12 DDRJCT'

list_string = string_1.split()

new_list = []

for i in range(len(list_string)):

if i == len(list_string) - 1:

new_list.append(list_string[i][-3:])

else:

new_list.append(list_string[i][-4:])

print(new_list)

output: ['RJ11', 'RJ12', 'RJ12', 'JCT']

Get last 4 characters of String in Java, In this post, we will see how to get the last n characters of a string in JavaScript. There are several methods to get last n characters from a string using JavaScript​  To find the last 4 digits, try this code. DATA: len TYPE i, str(10) TYPE c VALUE 'abcdefghij', substr TYPE string. len = STRLEN( str ) - 4. substr = str+len(4). WRITE: / substr. And regarding the file uploading, if you want to upload file fro the GUI Server, you can use the function module . GUI_UPLOAD.

There are many methods to solve this problem some of them are discussed below: How to find out which character key is pressed using JavaScript? This question explicitly asks for the last four characters in the string. You seem to be answering a different question related to extracting things from the middle of the string. Also Substring already lets you pass in a start point and length so not sure why you wouldn't use that rather than using Remove to remove the beginning first.

How to get the last character of a string in JavaScript , The index of the first character is 0, while the index of the last character is length​()-1 . If you want to get more than one consecutive character from a string, you can use the Here are some other String methods for finding characters or substrings Use this method when you only need to know that the string contains a  Create a computed column that is the string in reverse order. Then what were the right (least significant) three characters is now the left (most significant) three characters. You then index that column and look for WHERE LEFT(reversed,3) = REVERSE('190'). (I'm bored, can you tell?)

Manipulating Characters in a String (The Java™ Tutorials , The len function returns the number of characters in a string: >>> fruit = "banana" To get the last character, we have to subtract 1 from length: length = len(fruit) last To see how this works, let's start with a few examples: >>> "His name is %s​. <cfset newstring=Right("Receipt", 2)> This should do it. Check out the string functions section on livedocs to get an idea of what string manipulation functions are available.

  • Is the condition of how many suffix characters you want dependent on the prefix characters (DDSP vs DDR) ? What should be done for rogue values such as DDSPRJ1729 or DDREXTREME ? Is the focus more concerned with removing the prefix or detecting and extracting a suffix ?
