Types of conditions you can handle

A user-written condition handler can, in general, intercept and process any condition, regardless of the language of the routine in which the condition occurred. This means that you can code a user-written condition handler to respond to condition tokens with any of the following facility IDs:

• CEE, representing Language Environment and POSIX-defined conditions
• EDC, representing C and C++ conditions
• IGZ, representing COBOL conditions
• FOR, representing Fortran conditions
• IBM®, representing PL/I conditions

In general, your user-written condition handler can use any of the Language Environment condition handling services. Specific exceptions follow:

• The ways in which you can resume after an IGZ condition of severity 2 or above are restricted. See Resuming execution after an IGZ condition occurs for details.
• If an IBM condition of severity 2 or above was raised, then you cannot issue a resume without first moving the resume cursor.

  This restriction does not apply to IBM conditions of severity 0 or 1, or any IBM conditions signaled using the PL/I SIGNAL statement.

• You cannot promote any condition to an IBM condition (one that belongs to PL/I). You can promote IBM conditions to conditions with facility IDs of CEE, EDC, FOR, or IGZ.
