Syntax
scan(str.exp, search.delimiters)Parameter(s)
| str.exp | Specifies the string to search. |
| search.delimiters | Specifies up to three user-definable characters to be searched for in addition to the system delimiters value, subvalue, and attribute. The user-defined characters must be separated by a system delimiter. |
Description
The following information applies to the scan() function:
- If the delimiter is found, the scan() function returns the numeric position where the occurrence was found.
- If the specified search delimiters or any system delimiters are not found, the scan() function returns 0.
Example(s)
Example 1
The following example returns the value 5 to the variable
d.position. This is
because the first occurrence of either \’\ or \"\ is
found in the fifth position of the string.
String = \The "first" or ’second’ name.\ d.position = scan(string,\’\:@am:\"\)
