Overview
The ScriptGetComments function scans a specified script file and returns a string containing any discovered pragma comments. Pragma comments are separate and distinct from program comments.
Syntax/Parameters
Syntax
string = ScriptGetComments ( [string source] );
Parameters
source
An optional string containing a qualified filename of the script to examine. If not provided, the currently executing script is used as the source.
Return Value
Returns a string containing the comments or empty on failure. If the script does not contain any pragma comments, an empty string will also be returned. Use the GetLastError function to retrieve a formatted error code. The IsError and IsNotError functions can be used to determine if an error occurred.
Remarks
Unlike program comments, pragma survive crunching and can then be used to convey information.
Pragma comments are created using the pragma C directive. For example:
#pragma C Title: Open File with Data View
#pragma C Level: 0
#pragma C Description: Tests direct open view.
#pragma C Functions: DataViewOpenFile
The string returned will be:
Title: Open File with Data View
Level: 0
Description: Tests direct open view.
Functions: DataViewOpenFile
While the content is user defined, certain structures are used for script security and identification.
The comments are added to the string on a line-by-line basis and separated with a 0x0D line-ending character. The last comment entry will be terminated with a line ending.
