GetBuildID Method 992

Applies To: Root

Description

This method is used to obtain the Build ID of a Dyalog executable or the checksum of a file.

The argument to GetBuildID is ⍬ or a single item as follows:

[1]

File name

character vector

The (shy) result is an 8-element character vector of hexadecimal digits that represents the Build ID.

If the argument is ⍬, the build id is that of the current version of Dyalog that is running the expression.

Note that although this method is designed to uniquely identify different versions of Dyalog by its checksum, it may be used to obtain a checksum for any arbitrary file.

Examples

      GetBuildID ⍬
38091b76
      GetBuildID 'E:\DYALOG81\DYALOG.EXE'
cbf0d376
      GetBuildID 'myfile'
4a29334d

Note that if the file does not exist, the result is 00000000.
