Text mode
20 R1=102
30 R2=17
40 IPrint 10, R1, R2
The output result is:
PL2 MNEMONICS
Units OK 102
Units failed 17
Note that the numbers are aligned, this is accomplished by specifying the
field-width of the display with the : modifier.
If you list the program, you will also notice that the IMAGE will take many PL lines.
Since only seven characters of an image will fit into a single PL-code line, the
logical IMAGE statement can span many pl-code lines. (In the same way a motion
profile with P DATA statements spans multiple PL lines.) But for convenience, the
firmware one-line compiler allows entry of a longer image.
You should also note the ”; End” comment after the last image statement in the
group. It shows where the logical image actually ends.
A logical image is terminated by alternately a NUL (\000) character, i.e. the
physical image statement has less than seven characters in it. If the last physical
IMAGE statement has seven characters, but the next statement is NOT an IMAGE,
the logical IMAGE is also terminated.
You need to look out for this, so you don’t continue an IMAGE by mistake.
10 Image ”This is”
11 Image ”an ima”
12 Image ”ge.\013\010”; End
20 IPrint 10 Will produce: “This is an image”
22 IPrint 11 Will produce: “an image”
20 IPrint 10
The length when entering an image is limited by the input buffer size, in practice
about 100 to 120 characters, depending on how many escape sequences that are
entered.
The length of a logical IMAGE is only limited to the amount of PL code space that
is available. Also note that in IPRINT you can use a register to specify what line the
image resides on.
A cursor addressing example, this will only work if you have an ANSI or VT100
compatible terminal connected, you must also have turned off the monitor
(code \002, see below) to get the desired effect.
10 Image ”\027[%D%;%DH”
20 IPrint 10,R1,40
For a VT100/ANSI compatible terminal, this will send a cursor addressing
sequence to row in R1 and column 40. Note the ”%” sign after the first ”D” in the
image, it is to delimit, the ”;” so it is not interpreted as a format modifier for the ”D”
format.
The following escape and control sequences are of interest in an image:
\002 Start of TEXT, this character is used to indicate start of text mode
printouts, it will disable the normal line-editor control-T and DISP
statements from sending characters, to allow the PL program to have
full control over what is sent.
\003 End of TEXT, allow standard line editor etc. to send characters.
