The LB command writes text (label) on the CRT display with alphanumeric characters specified in the program.
The text characters are each specified by 8 bits in a 12-bit data word which immediately follows the LB command.
(The 4 most significant bits in the data word are set to 0.) The decimal equivalent of the binary number formed by
the 12-bit data word corresponds to a particular one of the available alphanumeric characters. Decimal numbers PI
through 255 and their corresponding characters are shown in the Character Set Table at the end of this command
description.
Characters generated for the LB command are aligned on the CRT in the same manner as typeset characters on a
printed page (that is, in rows and columns). This alignment is important when you are labeling graph lines or
points.
The display size specified by the display size command (Dl, D2, D3), or the "big expand (hex)" instruction,
determines the position of the text on the CRT, the number of rows and columns, and the size of the characters.
A typical use of the LB command is shown in the sample program below.
