IMOD Naming Conventions

The IMOD names can be up to 16 characters in length. The following restrictions apply:

An IMOD name must not start with a dollar sign ($). CA reserves names beginning with a dollar sign for their use.
An IMOD name uses only characters that are supported for standard REXX labels. For example, if you name an IMOD ABC.XYZ, REXX does not support the statement, CALL ABC.XYZ. The IMOD name is treated as a stem variable instead.
The underscore character (_) has special meaning in an IMOD name. It is used for name prefixing.
