mid$ and mid$$   function



Syntax:
subString$ = mid$(string$,startPos [,numChars])
subContainer$$ = mid$$(container$$,startPos [,numChars])


Description:
This function returns a substring or subcontainer of string$ or container$$, consisting of characters which begin at position startPos within string$ or container$$. If you specify numChars, then a maximum of numChars characters are returned; otherwise, all the characters from startPos to the end of string$ or container$$ are returned. If startPos is less than 1, then it's treated as 1. If startPos is greater than the length of string$ or container$$, then a null (zero-length) string is returned.

Note:
You may not use complex expressions that include containers on the right side of the equal sign. Instead of using:
c$$ = c$$ + mid$$(a$$,10)
Use:
c$$ += mid$$(a$$,10)

Example:
print mid$("Rick Brown", 2, 3)
myContainer$$ = "Rick Brown"
print mid$(myContainer$$, 2, 3)
print mid$("Rick Brown", 6)

program output:
ick
ick
Brown
