NAT0151: Invalid map name in INPUT statement.

Text	Invalid map name in INPUT statement.

Actn.	Check program and correct error.

NAT0152: Invalid map format in INPUT statement.

Text	Invalid map format in INPUT statement.
Expl.	The name of a map to be used in an INPUT statement may be specified as a literal alphanumeric constant or the content of an alphanumeric variable. If a variable is used, it must have been previously defined.
Actn.	Check program and correct error.

NAT0153: Format definition not allowed for a group name.

Text	Format definition not allowed for a group name.
Expl.	A group name is used to refer to a collection of fields as a single structure. Since this structure is defined by the formats of these fields, the group name need not have a format definition. If a field of one format is to be redefined as fields of differing formats, the REDEFINE statement should be used. Another possible cause of this error is that the level number of the next variable definition is higher than that of the variable marked, although both variables should probably be at the same level.
Actn.	Remove the format definition at the group name level, or make sure that the level numbers are correct.

NAT0155: Map name must not be longer than 7 characters.

Expl.	In a DIVIDE statement, you can use either the ROUNDED option to have the result of the division rounded, or the REMAINDER option to have the remainder of the division placed into a separate field. As there can be no remainder with a rounded result, it obviously makes no sense to use both options at the same time and is therefore not permitted.
Actn.	Use ROUNDED option or REMAINDER option, but not both.

NAT0162: Floating format not allowed for DIVIDE REMAINDER.

Text	Floating format not allowed for DIVIDE REMAINDER.

Text	Illegal syntax for variable name.
Expl.	- In a DEFINE DATA statement, the level specification must be followed by a valid name of a variable, group or view. - In a DEFINE DATA INDEPENDENT statement, - a variable name has to start with a "+" character (AIV variable); - the name of a field resulting from the redefinition of an AIV variable must not start with a "+" character. - A variable name starting with "+" (AIV) cannot be used in a PARAMETER, OBJECT, LOCAL or CONTEXT clause of a DEFINE DATA statement. See Natural Statements / Statement Usage Related Topics / User-Defined Variables / Naming Conventions and DEFINE DATA statement, for rules on naming variables.
