I have multiple datasets with many variables that begin with '/bic/ and end with 'n.
Does anyone know of a macro that will remove these characters from the beginning and end of variables with these specific characters?
For example, '/bic/ZHRIMMNA'n should be ZHRIMMNA while variables without these characters would be left alone.
Thank you.
OP's SAS table was imported from third party, as a result, the variable names is in literal. In EG, literals can be used by default, while if you are on Base, you may need to set the system option as: options validvarname=any;

Something like the following may fit your bill:
data have;
input '/bic/var1'n '/bic/var2'n;
cards;
1 2
;
proc sql;
select cats("'",name,"'N","=", scan(name,2,"/")) into :ren separated by ' '
from dictionary.columns
where LIBNAME='WORK' AND MEMNAME='HAVE';
QUIT;
DATA WANT;
SET HAVE;
RENAME &ren;
RUN;

Haikuo, does this SQL code ignore variables that don't begin with '/bic/ and end with 'n?
I haven't been able to test it yet.
Your datasets are SAS dataset ? The first character of SAS variable name must be an English letter (A, B, C, . . ., Z) or underscore (_).
My data is coming from SAP. It comes into SAS fine. However, I need to rename the variables after they come in as you stated above.

Thank you, I learn something new.
You granted me the "correct answer" before I deliver a correct one. The previous one only works if all of your variables are in the format of /bic/, you would need more fire power than scan() function if you want to ignore those not in literals.
data have;
input '/bic/var1'n '/bic/var2'n var3;
cards;
1 2 3
;
proc sql;
select cats("'",name,"'N","=", prxchange('s/\/bic\///io',-1,name)) into :ren separated by ' '
from dictionary.columns
where LIBNAME='WORK' AND MEMNAME='HAVE';
QUIT;
DATA WANT;
SET HAVE;
RENAME &ren;
RUN;
