PUTASSIGNTEXT
Appropriate text values for ASSIGN message parts are
cplist
is a checkpoint list in which the routine records the changes to the message
storage data space. Example:
01 CP-LIST-1.
05 MAX-COUNT PIC 9999 COMP VALUE IS 100.
05 CURRENT-COUNT PIC 9999 COMP VALUE IS 0.
05 ELEMENT PIC 9(9) COMP OCCURS 100 TIMES.
The initial value of MAX-COUNT must be the same as the number of occurrences
of ELEMENT.
In the non-CRE environment, the initial value of MAX-COUNT is the maximum
number of elements that cplist can contain. In the CRE, the maximum number
of elements that cplist can contain is the initial value of MAX-COUNT divided
by 2.5. The cplist in the preceding example can contain 100 elements in the
non-CRE environment, but only 40 in the CRE.
The required number of table elements depends on the number of operations the
list must record. The worst-case situation uses six elements.
A complete checkpoint list is required only when a program has a backup that must
be kept current. When a record of changes is not required, a null checkpoint list
can be used. This is an example description:
03 CP-LIST-1 PIC 9(9) COMP VALUE IS 0.
message-number
identifies a specific ASSIGN message. message-number can be a DISPLAY or
COMPUTATIONAL numeric data item, a numeric literal, or an expression enclosed
in parentheses. The value must evaluate to a positive integer. Example:
05 MESSAGE-NUMBER PIC S9999 COMPUTATIONAL.
LOGICALNAME The text contains the program unit name and the logical
file name, formatted like this, with a maximum of 63
characters:
programunit.filename
If the logical name does not include the program unit
name, the text contains only this, with no qualifier:
filename
TANDEMNAME The text is the file-system file name and can have a
maximum of 35 characters. The file name can be all
spaces.
