MID$ function

Purpose: MID$ returns a substring of a string.


 Syntax: 

 SubStr$ = MID$(MainStr$, Start% [, Length%])

 Parameters:

  • MainStr$ String from which SubStr$ is extracted.
  • Start% Integer specifying the start position of the SubStr$ to be extracted from MainStr$.
  • Length% [OPTIONAL] Length of the substring to be extracted. This can be omitted if all the characters to the right of Start% are to be retrieved.

 Return Value:

  • SubStr$, the return value, is a substring extracted from MainStr$.

Remarks: It is the responsibility of the programmer to ensure that the receiving string is large enough to hold the string being returned from MID$.
