Beginning in the fifth maintenance release of SAS 9.4 (TS1M5), formatting character strings in PROC FCMP might result in invalid characters in a multi-byte character encoding. Applying the format in a single-byte encoding such as WLATIN1 or LATIN1 displays the correct characters. In prior releases, a multi-byte character encoding such as UTF8 generated equivalent results as LATIN1 or WLATIN1 encoding.

If you do not know your SAS session encoding, you can look in the log after submitting: 

You can submit the code on the Full Code tab to replicate the problem.

Note: This issue is fixed in Rev. 940_18w30.

* For software releases that are not yet generally available, the Fixed Release is the software release in which the problem is planned to be fixed.

Using SAS 9.4 TS1M5, a PROC FCMP function that formats a character string might produce incorrect results if you are running SAS in a multi-byte session encoding. The code below illustrates this issue.

If you run the following example code using SAS in WLATIN1 session encoding, you will see a hexadecimal representation of 'TESTING' in EBCDIC:

result=E3C5E2E3C9D5C7

However, if you run the same test with session encoding UTF8 in SAS 9.4 TS1M5, the last character is truncated:

result=E3C5E2E3C9D5

---

proc fcmp;
   length mystr $ 64 result $ 64;
   mystr = 'TESTING: ';
   result = putc(putc(mystr, '$EBCDIC7.'), 'HEX64.');
   put result=;
run;

A fix for this issue for SAS Thread-safe Compiler and Symbolic Differentiator 9.45 is available at:

A fix for this issue for SAS Compiler and Symbolic Differentiator 9.44 is available at:

https://tshf.sas.com/techsup/download/hotfix/HF2/B8D.html#62380

PROC FCMP function results might be different in a UTF-8 SAS session encoding. A hot fix is available to improve character string manipulation within PROC FCMP to restore the behavior from the fourth maintenance release of SAS^® 9.4 (TS1M4).
