Building a Macro Macro command statements can be created from a library of CRISTAL macro functions. These macro functions are the basic building blocks for developing program applications. A macro command from the built-in macro list is written to a cell in the worksheet just like any other data entry operation. The parameters specified within macro commands can be modified or changed with the same cell editing procedures that are used to edit numeric, formula, or text cells. A macro is created by opening a cell with the ampersand symbol, "&." As the first character of all macro commands, the "&" initializes the cell data contents as a macro procedure. Macros must be accurately expressed in a predefined syntax, or the statements will not be recognized by CRISTAL and an error flag will be displayed in that cell. A macro statement records specified keyboard functions and commands into a cell or a sequential column of cells. Having completed the macro entry, a name can be assigned to the macro by pressing the [Alt F10] key sequence to activate the Macro Manager. The developer must select the "Add" command from the Manager menu and use the arrow keys to position the Highlight Bar at the desired line in the Manager list. The developer enters the macro name and the cell address (location) where the macro command set begins. The [Name,Cell] label can be a maximum of 27 contiguous characters. (Example: CYCLIC_MAINT_88,W250) Once named, the specified macro can be executed from the Macro Manager index by referencing the assigned name. Index to the Appendices Prototypes Macro Placement
