FEV. Enumeration Command
For each Variable
Intention
Enumerate all lines in a given variable.
Checks first if the Lines are delimited with CR,LF or CRLF and chooses the right Line-Separator.
If you load a complete Text-file into a variable using CFF. (Copy from file), you can go through each line of the text very fast, using FEV.
As FEV. work in Memory, its much faster then FEL. (For each line) that works on the file-system.
Syntax
FEV.P1|P2|P3[|P4]
Parameter Explanation
P1 - Label where the for each will jump "for each element"
P2 - Temp. Variable, updated by FEX each round.
P3 - Variable with Text
P4 - optional Standard-Pattern
