That will remove all instances.

To delete just the final non-blank character you can use ARGLEN (to determine its position) and SUBSTR.

Are these dialog manager & variables, or Focus fields? If the latter, are they fixed or variable in length?

There is a REVERSE subroutine. You can flip the contents, check to see if the firt character is a comma, remove it, then flip it back.

Hi Gopinath,
Can you try this below?

-SET &TEST = 'All,1,2,3,';
-SET &TEST1 = SUBSTR(&TEST.LENGTH, &TEST, 1, &TEST.LENGTH-1, &TEST.LENGTH-1, 'A&TEST.LENGTH');
-TYPE &TEST1

Gobinath,

I think you can use TRIM:
  
-* File strip1.fex
-SET &ST='A1,A2,A34,';
-SET &STL=&ST.LENGTH;
-SET &STM=TRIM('T','&ST.EVAL',&STL,',',1,'A&STL.EVAL');
-TYPE &ST : &STM

However, if the ',' is not the last character in your string and you have trailing blanks, then you should also r-justify your string:
  
-SET &ST='A1,A22,A3425,    ';
-SET &STL=&ST.LENGTH;
-SET &STM=LJUST(&STL, TRIM('T',RJUST(&STL,'&ST.EVAL','A&STL.EVAL'),&STL,',',1,'A&STL.EVAL'),'A&STL.EVAL');
-TYPE &ST : &STM
