有人可以向我解释为什么在.po
(“页面偏移量”)请求中嵌入文字值(例如,“1c”)有效但引用数字寄存器不起作用?
.\" Set the dimensions of an A4 page.
.nr a4_width 21c
.nr a4_height 29.7c
.nr a4_margin_horizontal 1c
.nr a4_margin_vertical 1c
.nr a4_content (\n[a4_width] - (\n[a4_margin_horizontal] * 2))
.
.\" Page-offset and line-length
.po \n[a4_margin_horizontal]
.ll \n[a4_content]
.\" Uncomment the below two lines and everything works.
.\" .po 1c
.\" .ll 19c
.
.\" Start the document.
