	What the ~~above~~ hello TEXAS line does:		What the first hello TEXAS line does:

	* Invokes the [[MUMPS Functions $PIECE\|Mumps function $P[iece]]], which is similar to but not exactly like the substring command in many other languages.		* Invokes the [[MUMPS Functions $PIECE\|Mumps function $P[iece]]], which is similar to but not exactly like the substring command in many other languages.

			What the second hello TEXAS line does:

			* invokes a FileMan function named $$GET1^DIQ which does the same thing as the first hello TEXAS line.
			& the first argument is the number of the file as the source of data.
