LANGUAGE ENVIRONMENT - CALLABLE SERVICES

 

Communicating Conditions Services

 

 CEEDCOD      Decomposes an existing condition token.  

 CEENCOD      Dynamically constructs a condition token.

  

Condition Handling Services

 

CEE3CIB           Given a condition token passed to a user-written condition handler

CEE3GRN          Get Name of currently running routine when a Condition raised.

CEE3GRO          Returns the offset of the most current Language                

CEE3SPM          Query and Modify Language Environment Hardware Condition     

CEE3SRP           Set Resume Point within user application code  

CEEGQDT          Retrieve data token from the  Instance-Specific Information (ISI)  

CEEHDLR          Register a User      

CEEHDLU          Unregister a User   

CEEITOK           Return Initial Condition Token

CEEMRCR          Move Resume cursor to the call return Cursor 

CEESGL             Signals a condition to the Language Environment condition manager.

 

Date and Time Services   

 

CEECBLDY       Convert Date into a COBOL Lilian date format.   

CEEDATE         Convert Lilian Date to Character Format such as "1992/07/25."     

CEEDATM         Convert Seconds to Ch Timestamp of seconds since14 October 1582  

CEEDAYS         Convert Date to  into a Lilian format. of days  since 14 October 1582.   

CEEDYWK        Calculate Day of Week from Lilian as a number between 1 and 7.   

CEEGMT           Get Current Greenwich Mean Time (GMT) as  a Lilian date  

CEEGMTO         Difference bw the local system time and Greenwich Mean  Time.  

CEEISEC           Converts year into the number of seconds since 14 October 1582.  

CEELOCT          Local Returns the current local time in three formats:                                                                           

                                Lilian date (the number of days since 14 October 1582)         

                                Lilian timestamp (the number of      

                                 seconds since 00:00:00 14 October 1582)                                

                                Gregorian character string (in the form YYYYMMDDHHMISS999)     

CEEQCEN         Queries the century within which LE assumes 2-digit year.  

CEESCEN          Sets the century where LE assumes 2-digit year values lie.  

CEESECI           Converts a number representing the number of seconds since 00:00:00 14 October 1582

                             to seven separate binary integers         

                             representing year, month, day, hour,     

                             minute, second, and millisecond. Use     

                             CEESECI instead of CEEDATM when the      

                             output is needed in numeric format rather

                             than character format.   

CEESECS        Converts a string representing a    timestamp into a number representing the 

                             number of seconds since 00:00:00 14       

                             October 1582. This service makes it      

                             easier to do time arithmetic, such as    

                             calculating the elapsed time between two timestamps.
