CEECBLDY converts a string that represents a date into the number of days since 31 December 1600. Use CEECBLDY to access the century window of the date and time callable services and to perform date calculations with COBOL intrinsic functions.
This service is similar to CEEDAYS except that it provides a string in COBOL integer format, which is compatible with COBOL intrinsic functions.

The character string must contain between 5 and 255 characters, inclusive. input_char_date can contain leading or trailing blanks. Parsing for a date begins with the first nonblank character (unless the picture string itself contains leading blanks, in which case CEECBLDY skips exactly that many positions before parsing begins).
After parsing a valid date, as determined by the format of the date specified in picture_string, CEECBLDY ignores all remaining characters. Valid dates range between and include 01 January 1601 to 31 December 9999.
Each character in the picture_string corresponds to a character in input_char_date. For example, if you specify MMDDYY as the picture_string, CEECBLDY reads an input_char_date of 060288 as 02 June 1988.
If delimiters such as the slash (/) appear in the picture string, you can omit leading zeros. For example, the following calls to CEECBLDY would each assign the same value, 141502 (02 June 1988), to COBINTDTE:
MOVE '6/2/88' TO DATEVAL-STRING. MOVE 6 TO DATEVAL-LENGTH. MOVE 'MM/DD/YY' TO PICSTR-STRING. MOVE 8 TO PICSTR-LENGTH. CALL CEECBLDY USING DATEVAL, PICSTR, COBINTDTE, FC.
MOVE '06/02/88' TO DATEVAL-STRING. MOVE 8 TO DATEVAL-LENGTH. MOVE 'MM/DD/YY' TO PICSTR-STRING. MOVE 8 TO PICSTR-LENGTH. CALL CEECBLDY USING DATEVAL, PICSTR, COBINTDTE, FC.
MOVE '060288' TO DATEVAL-STRING. MOVE 6 TO DATEVAL-LENGTH. MOVE 'MMDDYY' TO PICSTR-STRING. MOVE 6 TO PICSTR-LENGTH. CALL CEECBLDY USING DATEVAL, PICSTR, COBINTDTE, FC.
MOVE '88154' TO DATEVAL-STRING. MOVE 5 TO DATEVAL-LENGTH. MOVE 'YYDDD' TO PICSTR-STRING. MOVE 5 TO PICSTR-LENGTH. CALL CEECBLDY USING DATEVAL, PICSTR, COBINTDTE, FC.
Whenever characters such as colons or slashes are included in the picture_string (such as HH:MI:SS YY/MM/DD), they count as placeholders but are otherwise ignored.
If picture_string includes a Japanese Era symbol <JJJJ>, the YY position in input_char_date is replaced by the year number within the Japanese Era. For example, the year 1988 equals the Japanese year 63 in the Showa era.
If input_char_date does not contain a valid date, output_Integer_date is set to 0 and CEECBLDY terminates with a non-CEE000 symbolic feedback code.
Date calculations are performed easily on the output_Integer_date, because output_Integer_date is an integer. Leap year and end-of-year anomalies do not affect the calculations.
| Symbolic feedback code | Severity | Message number | Message text |
|---|---|---|---|
| CEE000 | 0 | — | The service completed successfully. |
| CEE2EB | 3 | 2507 | Insufficient data was passed to CEEDAYS or CEESECS. The Lilian value was not calculated. |
| CEE2EC | 3 | 2508 | The date value passed to CEEDAYS or CEESECS was invalid. |
| CEE2ED | 3 | 2509 | The era passed to CEEDAYS or CEESECS was not recognized. |
| CEE2EH | 3 | 2513 | The input date passed in a CEEISEC, CEEDAYS, or CEESECS call was not within the supported range. |
| CEE2EL | 3 | 2517 | The month value in a CEEISEC call was not recognized. |
| CEE2EM | 3 | 2518 | An invalid picture string was specified in a call to a date/time service. |
| CEE2EO | 3 | 2520 | CEEDAYS detected nonnumeric data in a numeric field, or the date string did not match the picture string. |
| CEE2EP | 3 | 2521 | The <JJJJ>, <CCCC>, or <CCCCCCCC> year-within-era value passed to CEEDAYS or CEESECS was zero. |
