The number of lines to be redisplayed. If you do not type a number, or if the number you type is 1, only one line is redisplayed
The SI (Show Indentation) line command causes one or more lines in a block of excluded lines to be redisplayed. The redisplayed lines have the leftmost indentation levels; they contain the fewest leading blanks.
Note that SI is the new name for the legacy ISPF line command of S. The SPFLite line command S now performs a different function. SPFLite has chosen to deviate from the ISPF standard here because the legacy Show Indentation feature is rarely used, and the SPFLite S/SS command performs a more important and useful operation.
If there are more than 2 excluded lines, and you do not type a number or if the number you type is 1, only one line is redisplayed.
Note: If you enter an SI line command to display all but one line of an excluded block, then that line is also displayed. This could result in more lines being displayed than the number you requested. For example, if five lines are excluded in a block, an SI4 command causes all five lines to be displayed.
