Nomad platform differences in LotusScript®
These platform differences apply to HCL Nomad for web browsers.
Language construct differences
| Construct |
Usage in HCL Nomad |
|---|---|
| ActivateApp |
Not supported. Generates the error "Operation not supported on this platform." |
| ChDir |
If a drive letter is contained in the argument, generates the error "Device unavailable." |
| CreateObject |
Not supported. Generates the error "Operation not supported on this platform." |
| Date, Date$ |

File system differences
Nomad for web browsers does not access the file system of the host operating system. It accesses only a virtual file system within the browser. This characteristic affects all functions related to the file system.
There are no drive letters on the virtual file system. All devices reside under the root directory. If you use a path name containing a drive letter, LotusScript® returns an error. (Note that since UNIX™ allows ":" in file names, the statement Dir$("a:") is legal. It searches the current directory for a file named a:.)
LotusScript® excludes "/" and "\" from the end of file paths, so if a file path ends with one of those characters, the file is created in the current folder instead. If the file path starts with "/" or "\" and doesn't end with "." or a file name extension, LotusScript® generates an error.
LotusScript® accepts file paths starting or ending with one or multiple "."
Other differences
OLE is not supported on LotusScript® Release 3.0 for Nomad platforms. This difference affects CreateObject, GetObject, IsObject, and IsUnknown. The CreateObject and GetObject functions generate run-time errors when executed on UNIX™ platforms. The IsObject function tells if a variable refers to a native or product object, but not an OLE object, since OLE objects don't exist on the UNIX™ platform. The IsUnknown function always returns FALSE on UNIX™, since there is no way for a Variant expression to receive the V_UNKNOWN value.
