Lines Command

The Lines command divides up a variable by lines:

Lines "(varName)",(start),(end),(expr)

where:

• "(varName)" is a valid string variable name in quotes (e.g., "#varName"), but not an array name followed by [(index)].
• (start) and (end) specify the range of lines to extract (first line is line number 1) or can be <=0 to specify line number relative to the end (0 is last line, -1 is next to last line, etc.).
• (expr) is a string or string expression possibly containing multiple lines.

When done, the results will be in the specified variable. If the qouted variable name is "#varName", for example, the extracted lines will be in #varName[1], #varName[2], etc., and the total number of lines will be stored in #varName[0].
