Template:YLM to do Currently only supports 1 parsing string - check and add example
Purpose
Function to fill an array with character strings that are separated with a newline or other specified parsing string
Syntax
ALINES(<array>, <expC1> [<expN> [, <expC2>]])

Description
The ALINES() function fills the <array> with character strings from <expC1> which are separated by a newline. If the optional <expC2> is included, it specifies an alternative parsing string. This string of one or more characters is used to signify where the line should be broken instead of the newline character.
If the <array> does not already exist it will be created. The character strings are copied into the array elements until all the strings are copied. If the <array> is pre-declared, it will be automatically shortened to the number of elements stored in it. The ALINES() function returns the number of character strings copied into the array.
The <expN> is the sum of the required flags:
| Bit | Value (additive) | Description |
|---|---|---|
| 0 | 1 | Removes leading and trailing spaces from lines, or for memos and BLOBs, removes trailing zeroes (0) instead of spaces. This is the default. |
| 1 | 2 | Include the last element in the array even if the element is empty. |
| 2 | 4 | Do not include empty elements in the array. |
| 3 | 8 | Case-insensitive parsing. |
| 4 | 16 | Include the parsing characters. |
Example
// ali.prg - 4 lines cVar=filetostr("ali.prg") nVar = alines(aVar, cVar) echo "Program has " + ltrim(str(nVar)) + " lines\n"
