Syntax
<Result> = fReadLineRegularExpression(<File used> , <Format> , <Variable 1> [, <Variable 2> [... [, <Variable N>]]])
<Result>: Boolean - True if the data was read and retrieved.
- False otherwise.
<File used>: Integer or DiskFile variable <Format>: Character string Reference format, expressed as a regular expression. This format uses the following characters:
| | | A B C - / _ | Letters and symbols to check | | [A-Z] or [0-9] | Interval of letters, digits or symbols to check | | * | 0 or more symbols to check | | + | 1 or more symbols to check | | ( ) | Delimit part of the format to extract | | { } | Defines the minimum and maximum number of times that the previous expression can occur (e.g., {min, max}) |
<Variable 1>: Character string, Integer, etc. Variables that will be automatically initialized with the different parts of the format to extract. Each part is defined by the '(' and ')' characters. <Variable 2>: Character string, Integer, etc. Variables that will be automatically initialized with the different parts of the format to extract. Each part is defined by the '(' and ')' characters. <Variable N>: Character string, Integer, etc. Variables that will be automatically initialized with the different parts of the format to extract.
