Syntax

%SYSRC(character-string)

character-string: is one of the mnemonic values listed in Mnemonics for Warning and Error Conditions or a text expression that produces the mnemonic value.

Note: Autocall macros are included in a library supplied by SAS. This library might not be installed at your site or might be a site-specific version. If you cannot access this macro or if you want to find out if it is a site-specific version, see your on-site SAS support personnel. For more information, see Storing and Reusing Macros.

Details

The SYSRC macro enables you to test for return codes produced by SCL functions, the MODIFY statement, and the SET statement with the KEY= option. The SYSRC autocall macro tests for the error conditions by using mnemonic strings rather than the numeric values associated with the error conditions.

When you invoke the SYSRC macro with a mnemonic string, the macro generates a SAS return code. The mnemonics are easier to read than the numeric values, which are not intuitive and subject to change.

You can test for specific errors in SCL functions by comparing the value returned by the function with the value returned by the SYSRC macro with the corresponding mnemonic. To test for errors in the most recent MODIFY or SET statement with the KEY= option, compare the value of the _IORC_ automatic variable with the value returned by the SYSRC macro when you invoke it with the value of the appropriate mnemonic.

The following table lists the mnemonic values to specify with the SYSRC function and a description of the corresponding error.

Comparison

The SYSRC autocall macro and the SYSRC automatic macro variable are not the same. For more information, see SYSRC Automatic Macro Variable.

Example

Example 1: Examining the Value of _IORC_

The following DATA step illustrates using the autocall macro SYSRC and the automatic variable _IORC_ to control writing a message to the SAS log:

data big;
   modify big trans;
   by id;
   if _iorc_=%sysrc(_dsenmr) then put 'WARNING: Check ID=' id;
run;
