SYSDATE- LONG is a 10-byte alphabetic field that contains the system date, including the century. Format is MM/DD/CCYY.
Usage: FIELD-ONE= SYSDATE
SYSTIME is an eight-byte alphabetic field that contains the system time. Format is HH.MM.SS.
Usage: FIELD-TWO = SYSTIME
PARM-REGISTER PARM-REGISTER is a four-byte binary field which contains the contents of register 1 upon entry to CA-Easytrieve/Plus. Register 1 contains the address of a passed parameter list. This address is accessed by the subprogram EZTPX01 when passing EXEC statement PARM parameters.
EZTPX01 is a called subprogram used to interrogate a PARM coded on a JCL EXEC statement. It is distributed with CA-Easytrieve/Plus.
EZTPX01 requires two parameters, the system defined PARM-REGISTER, and a user defined input/output field. The input/output field must consist of a 2-byte binary field immediately followed by a character portion to contain the actual PARM information.
You are responsible for placing the maximum length you expect for the PARM information (the character portion) into the 2-byte binary field before calling EZTPX01. EZTPX01 moves your PARM data from your JCL EXEC statement into the character portion of your input/output field and updates the length in the 2-byte binary portion.
RETURN-CODE is a four-byte binary field whose contents are returned to the operating system in register 15. RETURN-CODE is initialized to zero, but you can set it to any value.
Usage: RETURN-CODE = 4
A – EBCDIC Alpha
N – Zoned Numeric
U – Unsigned Packed
P – Packed
B – Binary
M – MIXED
K – DBCS / Kanji
i) Nested IF (as we use in cobol we can use)
ii) DO WHILE NOT EOF file1
iii) PERFORM statements ==> we use to call procs
Ex: Perform First-proc
