You may be better off using a SUBSTR() function?

Looks like you're taking first character and then everything after the 4th?

I'm not sure this will easily extend if needed but works for the example data;

data example;
   informat test $10.;
   input test;
   result = tranwrd(test,'EXCL0','E');
   result = tranwrd(Result,'EXCL','E');
datalines;
EXCL01
EXCL07B
EXCL08
EXCL08C
EXCL10
;
