nested procedure造句

where n specifies the difference in nesting levels ( remember that Pascal supports nested procedures ).
On the other hand, register machines must spill many of their registers to memory across nested procedure calls.
The BEGIN SEQUENCE structure allows for a well behaved abortion of any sequence, even when crossing nested procedures / functions.
This could cause difficulty for some systems that generated Algol source as output ( tailored to solve some special problem ) if the generation method frequently nested procedure within procedure.
A deeply nested procedure ( thus at a high lexical level ) would have fewer bits available to identify entities, and so for level sixteen upwards their number was restricted.
It's difficult to find nested procedure in a sentence. 用nested procedure造句挺难的

However, since Pascal has nested procedures / functions, jumps can be done from an inner procedure or function to the containing one; this was commonly used to implement error recovery.
This spilling effect depends on the number of hidden registers used to buffer top-of-stack values, upon the frequency of nested procedure calls, and upon host computer interrupt processing rates.
Procedural parameters were provided also in Pascal, together with nested procedure definitions; however, since standard Pascal did not allow separate compilation, the feature was little used in that language, too.
Pascal, like many programming languages of today ( but unlike most languages in the C family ), allows nested procedure definitions to any level of depth, and also allows most kinds of definitions and declarations inside subroutines ( procedures and functions ).
This means that a called procedure / function, may issue a BREAK statement, or a Break ( ) expression, to force unfolding of any nested procedure / functions, all the way back to the first outer BEGIN SEQUENCE structure, either after its respective END statement, or a RECOVER clause if present.
