2. if-else Statement The if-else statement is used to perform operations based on a predefined condition. If the condition is true, the code inside the if block is executed. Otherwise, the code inside the else block is executed. if-else Statement Syntax: ...
Otherwise, use an IF-THEN-ELSE statement. Example 複製 CASE Field OF Field::A: BEGIN x := x + 1; y := -y - 1; END; Field::B: x := y; Field::C,Field::D: y := x; ELSE BEGIN y := x; a := b; END; END Example The following C/AL code prints various messages ...
A continue statement in a for statement causes evaluation of the loop expression of the for statement. Then the code reevaluates the conditional expression. Depending on the result, it either terminates or iterates the statement body. For more information on the for statement and its nonterminals...
/*While Loops*/ while(conditional-expression) { nested-statements } /*For Loops*/ for(initialization; conditional-expression; increment) { nested-statements } /*Do-While Loops*/ do{ nested-statements }while(conditional-expression); Conditional Execution And Selection /*If Statements*/ if(conditiona...
Code that sets up the context forifandwhileconstructs should be separated fromifandwhileby a blank line, unless the body ofifandwhileconsists of a single statement: package = strtok(buf,"\n");while(NULL != package){...package = strtok(NULL,"\n");} ...

You can nest several WITH statements. If you have identical names, then the inner WITH statement overrules the outer WITH statement. Example This example shows two ways to write the same code that creates a record variable that you can commit later. ...
lint Source Code Checker This chapter explains how you can use the lint program to check your C code for errors that may cause a compilation failure or unexpected results at runtime. In many cases, lint warns you about incorrect, error-prone, or nonstandard code that the compiler does not...
Use a pure-block, fully bracketed style for blocks of code. This means put brackets around all conditional code blocks, even one-line blocks. if(statement ==true) {foo_true(); }else{foo_false(); } 2.5 Spaces Insert space padding around operators. E.g., ...
