IB Statements/noexcp
From CometWiki
NOEXCP option on file system statements
Parameter: NOEXCP
Discussion:
Introduced with Comet32 this parameter may be used in file system statements to specify that if a non-fatal runtime exception occurs it should be ignored.
This option is available for:
ERASE, ENTER, EXTRACT, CREATE, CREATEKEY, DELETE, INPUT, INPUTFILE, INQUIRE, INSERT, POSITION, PRINTFILE, PRINT, OPEN, UPDATE, READ, RENAME, REWRITE, RUN, LOCK, UNLOCK, WRITE.
For information about handling specific exceptions, see Exception Handling.
Note that the EXCP variable will still contain the last exception encountered, and will not be set to zero. This allows a form of "goto less programming"
Also see ExcpSub
Example:
EXCP=0 ERASE file$ dir=dir$ NOEXCP CREATE file$ dir=dir$ NOEXCP Close(LUN) & OPEN(LUN)file$ dir=dir$ NOEXCP if EXCP ne 0 print 'got an error ';EXCP;' creating ';file$
