Hello Oliver,
regarding your question 2. to avoid linebreaks I believe
the main issues are within the while loop:
- leading blank space before \n+[mynum]
- missing \c after \n+[mynum]
- missing leading . before the \}
The following achieves what I think you are looking for:
.while (\n[mynum] < \n[@count]) \{
. barcode 9876543210 \n[mynum]
\n+[mynum]\c
.\}
In addition I'd like to recommend the following minor
improvements—although not strictly necessary I think
they are good practice—as they have helped me avoid
pitfalls in the past:
- adding a \ for line continuation to the opening curly brace
on the while line
- using nop to indent the \n+[mynum] line
- decrementing the while loop counter in the while condition
.nr mynum \n[@count] 1
.while (\n-[mynum] > 0) \{\
. barcode 9876543210 \n[mynum]
. nop \n[mynum]\c
.\}
Hope this helps, and please do share your progress on barcodes,
I'm curious!
Best
Alexis
