Print image line and AEDITX$.
Description
The image pointed to by the image location in the packet is
printed and AEDITX$ performed. The line spacing is given in
p1. If the parameter is omitted, a value of one is used.
The AEDIT$ routines do not limit the size of the image that can
be created. However, the size of the image that can be
printed is limited by both the AEPRINT$ routine and the
current print width.
The AEPRINT$ routine has a limit of 63 words or 252 ASCII
characters. If the image contains more than 63 words,
AEPRINT$ prints the first 63 words and ignores the extra
words.
The print width is a control parameter for the Exec printer
handlers. If the length of the image is greater than the current
print width, a type 02 (SYMB) code 04 (SDF image length
error) contingency occurs.
The standard default value for print width is 33 words or 132
ASCII characters. To print an image larger than this, you must
increase the print width by using the print control 'W' function.
Refer to the Exec Request Programming Reference Manual for
a description of the print control functions.
Note: To establish the print width for the maximum size
image that can be output by AEPRINT$ (63 words or 252 ASCII
characters), issue a print control "W,42" function. With this
print width, no contingency due to length error will ever occur
when using AEPRINT$. This is because AEPRINT$ prints a
maximum of 63 words of image data and ignores any words
beyond 63.
Advance the column pointer.
The number given in p1 is added to the column pointer.
p1 may be negative.
