StringMid()
OutputVar := Mfunc.StringMid(Input, StartChar [, Count , L])
Retrieves one or more characters from the specified position in a string.
Input
The name of the variable from whose contents the substring will be extracted.
StartChar
The position of the first character to be extracted, which can be an expression. Unlike Mfunc.StringGetPos, 1 is the first character. If StartChar is less than 1, it will be assumed to be 1. If StartChar is beyond the end of the string, OutputVar is made null (blank).
Can be MfInteger instance or var containing integer.
Count
In AutoHotKey [v1.0.43.10+], this parameter may be omitted or left blank, which is the same as specifying an integer large enough to retrieve all characters from the string.
Otherwise, specify the number of characters to extract, which can be an expression. If Count is less than or equal to zero, return value will be made empty (blank). If Count exceeds the length of Input measured from StartChar, return value will be set equal to the entirety of Input starting at StartChar.
Can be MfInteger instance or var containing integer.
L
The letter L can be used to extract characters that lie to the left of StartChar rather than to the right.
Can be var containing the value of L or MfString containing the value of L.
In the following example, return value will be set to Red:
Input = The Red Fox
OutputVar := Mfunc.StringMid(Input, 7, 3, "L")
If the L option is present and StartChar is less than 1, return value will be made null (empty). If StartChar is beyond the length of Input, only those characters within reach of Count will be extracted. For example, the below will set return value to Fox:
Input = The Red Fox
OutputVar := Mfunc.StringMid(Input, 14, 6, "L")
Returns the substring extracted from Input.

InputVar := "The quick brown fox jumps over the lazy dog."
result := Mfunc.StringMid(InputVar , 21, 5)
MsgBox, %result% ; Displays: jumps
result := Mfunc.StringMid(InputVar , 21, 5, "L")
MsgBox, %result% ; Displays: fox j
mfsInputVar := new MfString(InputVar)
mfsL := new MfString("L")
result := Mfunc.StringMid(mfsInputVar , 21, 5)
MsgBox, %result% ; Displays: jumps
result := Mfunc.StringMid(mfsInputVar , 21, 5, mfsL)
MsgBox, %result% ; Displays: fox j
