Error Numbers and Messages

The error numbers produced by syntax errors during the processing of Rexx programs are all in the range 1 to 99. Errors are raised in response to conditions, for example, SYNTAX, NOMETHOD, and PROPAGATE. When the condition is SYNTAX, the value of the error number is placed in the variable RC when SIGNAL ON SYNTAX is trapped.

You can use the ERRORTEXT built-in function to return the text of an error message.

Some errors have associated subcodes. A subcode is a one- to three-digit decimal extension to the error number, for example, 911 in 19.911. When an error subcode is available, additional information that further defines the source of the error is given. The ERRORTEXT built-in function cannot retrieve the secondary message, but it is available from the condition object created when SIGNAL ON SYNTAX traps an error.

Note that some of below listed error messages may not actually be used by the interpreter, but are being retained for compatibility with existing Rexx code or libraries.
