Chapter 10 Generating a Database from a PDM
Variables have a syntax that can force a format on their values. Typical uses are as follows:
You embed formatting options in variable syntax as follows:
%[[?][-][width][.[-]precision][c][H][F][U|L][T][M][q][Q]:]<varname>%
The variable formatting options are the following:
| Format option | Description |
|---|---|
| ? | Mandatory field, if a null value is returned the translate call fails |
| n (where n is an integer) | Blanks or zeros added to the left to fill the width and justify the output to the right |
| -n | Blanks or zeros added to the right to fill the width and justify the output to the left |
| width | Copies the specified minimum number of characters to the output buffer |
| .[-]precision | Copies the specified maximum number of characters to the output buffer |
| .L | Lower-case characters |
| .U | Upper-case characters |
| .F | Combined with L and U, applies conversion to first character |
| .T | Leading and trailing white space trimmed from the variable |
| .H | Converts number to hexadecimal |
| .c | Upper-case first letter and lower-case next letters |
| .n | Truncates to n first characters |
| .-n | Truncates to n last characters |
| M | Extracts a portion of the variable name, this option uses the width and precision parameters to identify the portion to extract |
| q | Enquotes the variable (single quotes) |
| Q | Enquotes the variable (double quotes) |
For more examples on variable formatting, see section Defining variable formatting options in the DBMS Resource File Reference chapter in the Customizing and Extending PowerDesigner manual.
