String functions are used in computer programming languages to manipulate a string or query information about a string (some do both). Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.
As an example, VBA code written in Microsoft Access can establish references to the Excel, Word and Outlook libraries; this allows creating an application that – for instance – runs a query in Access, exports the results to Excel and analyzes them, and then formats the output as tables in a Word document or sends them as an Outlook email.
In many computer programming languages, a do while loop is a control flow statement that executes a block of code and then either repeats the block or exits the loop depending on a given boolean condition. The do while construct consists of a process symbol and a condition. First the code within the block is executed.
Microsoft Excel is a spreadsheet editor developed by Microsoft for Windows, macOS, Android, iOS and iPadOS.It features calculation or computation capabilities, graphing tools, pivot tables, and a macro programming language called Visual Basic for Applications (VBA).
for i from f by b to t while w do # loop body od; All parts except do and od are optional. The for I part, if present, must come first. The remaining parts (from f, by b, to t, while w) can appear in any order. Iterating over a container is done using this form of loop: for e in c while w do # loop body od;
The loop calls the Iterator::next method on the iterator before executing the loop body. If Iterator::next returns Some(_) , the value inside is assigned to the pattern and the loop body is executed; if it returns None , the loop is terminated.
Another, less common, use of macros is to do the reverse: to map a sequence of instructions to a macro string. This was the approach taken by the STAGE2 Mobile Programming System , which used a rudimentary macro compiler (called SIMCMP) to map the specific instruction set of a given computer into machine-independent macros.
Other processes can use the CPU while the caller is blocked. The scheduler is given the information needed to implement priority inheritance or other mechanisms to avoid starvation . Busy-waiting itself can be made much less wasteful by using a delay function (e.g., sleep() ) found in most operating systems.
