MOVE (MV)
Direct
In this variant, characters are taken from the first data item, starting at a specified position
and continuing for a specified length. The characters are moved into the second data item,
starting at a specified position, overwriting the current characters. Characters not
overwritten are retained.
Sorted
This variant is indicated by specifying either the SORTA; (ascending) or SORTD;
(descending) command option.
A group of characters is taken from the first data item, starting at a specified position and
continuing for a specified length. This group of characters is inserted into the second data
item. The position of the insertion is determined by grouping characters in the second data
item into groups (the same size as the group from the first data item), and then comparing
the group to be inserted with each group in the second data item.
The size of the value of the second data item increases with each MOVE; command.
Truncation may occur if the value exceeds the length of the second data item. If the last
right-hand significant group of figures do not have their position changed, truncation will
not take place.
Spaces are not sorted.
Setting GLB.STATUS
The MOVE; command is validated if any of the following situations apply:
$ The Def bounds checking field on the Primary Specification Options screen is set to
Y.
When this field is set to N, error checking code is not generated, so a check for errors
will not occur. This means that if a complex move is performed that is out of bounds of
the receiving data item, that data item may contain unpredictable results.
$ The GLB.STATUS; command is included in the MOVE; command.
$ The sorted variant of the MOVE; command is used.
If validation is in effect, it proceeds as follows.
$ If an invalid MOVE; command is attempted, ***** is moved to the System Data item
GLB.STATUS, and the move is not performed.
$ If truncation occurs, GLB.STATUS is not usually set to *****. However, if a group of
characters in a sorted complex MOVE; command is appended to the second data item
and would be truncated, GLB.STATUS is set to ***** and the move is not performed.
