| ☜ | $QLENGTHM[UMPS] by Example | ☞ | ||||
Introduced in the 1995 ANSI M[UMPS] language standard.
This function returns information about the number of subscripts in a name-reference.
Assume that the following references are made in this order:
| Reference | Value | |
|---|---|---|
| $Data(^|"XXX"|ABC(1,2,3,4)) | 0 | |
| Set X=$NAme(^(5,6)) | X="^|""XXX""|ABC(1,2,3,5,6)" | |
| $QLength(X) | "5" |
Note that this function only operates on the string that contains the name of a variable. The variable that is identified in this string is never accessed by this function. Therefore, this function only affects the naked indicator if the string in question is stored in a global variable.
For additional examples of this function, see the function $NAme.
