You could use the IIDELAY macro to suspend execution long enough
for you to make sure the printer is ready to print.
The execution time of a IIDELAY macro will vary slightly according to
the speed TRSDOS is running under (FAST or SLOW). See the
SYSTEM library command.
IIEXIT
Use this macro to halt execution
of
JCL processing and return to the
program that initiated the DO command.
If you do not enter a termination macro in a JCL file, the
JCL
processing terminates when it reaches the end of the file (as if IIEXIT
were the last line
in
the
JCL
file). The following message is displayed:
Job
done
This message indicates a normal conclusion of the
JCL
file.
You should use
IIEXIT if the conclusion of the
JCL
file also represents
the conclusion of the job that is running. So,
IIEXIT can be used to
conclude a program that does not require any more keyboard input,
and needs to return to TRSDOS Ready or BASIC Ready after it
finishes.
To conclude a program that requires additional keyboard input, use
the
IISTOP macro. Using the IIEXIT macro would terminate the
program.
IIFLASH
[duration]
message
This macro flashes message on and off the video screen. duration is
the number of times the
message will flash and can be any number
from
0 to 255. If duration is not specified, the message flashes 256
times. The message
is
any comment that you want displayed (up to
72 characters).
IIKEYIN
[comment
string]
Use this macro to prompt for a single character entry
(0
- 9), with the
entire IIKEYIN line being displayed.
During execution, press the appropriate character
(0
-
9)
to select the
corresponding execution block
in
a JCL file. There can be up to ten
execution blocks
in
a JCL file, each tagged with II and a number 0 -
9.
Do not use IIKEYIN to enter data at execution time. If you do need to
enter data at execution time, use the IIINPUT macro.
IIINPUT
[message
string]
Use this macro to input a line from the keyboard during
JCL
execution. With this macro, control of the keyboard is temporarily
