StrFormat()

StrFormat()

Format a string

Syntax

      StrFormat(<cMask>[, <cPar1>[, <cParn>[, ...]]) --> cString

Arguments

<cMask> Holds the mask for the resulting string

<cParn> Holds the strings to be inserted in the mask maximum 9 of them can be specified.

Returns

<cString> Return the mask with all the parameters inserted.

Description

String replacment, can be useful when writing international apps. You can separate the constant strings from the variable ones. Each %1 – %9 marks will be replaced with the appropriate parameter from the parameter list.

Marks can be in any order, and can be duplicated.

You can print “%” character with “%%”.

Examples

      StrFormat( "Please insert disk %1 to drive %2", hb_ntos( 2 ), "A:" )
      StrFormat( "This is %1 from %2", "Victor", "Hungary" )
      StrFormat( "%2 %1 %2", "Param1", "Param2" )

Tests

      ? StrFormat( "Please insert disk %1 to drive %2", hb_ntos( 2 ), "A:" )
      ? StrFormat( "This is %1 from %2", "Victor", "Hungary" )
      ? StrFormat( "%2 %1 %2", "Param1", "Param2" )
      ? StrFormat( "Hello" )
      ? StrFormat( "%1 - %2", "one" )
      ? StrFormat( "%1 - %2", "one", "two" )
      ? StrFormat( "%2 - %1", "one", "two" )
      ? StrFormat( "%2 - %", "one", "two" )
      ? StrFormat( "%% - %", "one", "two" )
      ? StrFormat( "%9 - %", "one", "two" )

MemoTran()

MEMOTRAN()

Converts hard and soft carriage returns within strings.

Syntax

      MEMOTRAN( <cString>, <cHard>, <cSoft> ) --> <cConvertedString>

Arguments

<cString> is a string of chars to convert.

<cHard> is the character to replace hard returns with. If not specified defaults to semicolon.

<cSoft> is the character to replace soft returns with. If not specified defaults to single space.

Returns

<cConvertedString> Transformed string.

Description

Returns a string/memo with carriage return chars converted to specified chars.

Examples

      ? MEMOTRAN( DATA->CNOTES )

Tests

      @ 1, 1 SAY MEMOTRAN( Data->CNOTES )
      will display converted string starting on row two, column two of the
      current device.

Examples

      ? HARDCR( Data->CNOTES )

 STRTRAN()
 Search and replace characters within a character string or memo field
------------------------------------------------------------------------------
 Syntax

     STRTRAN(<cString>, <cSearch>,
        [<cReplace>], [<nStart>], [<nCount>]) --> cNewString

 Arguments

     <cString> is the character string or memo field to be searched.

     <cSearch> is the sequence of characters to be located.

     <cReplace> is the sequence of characters with which to replace
     <cSearch>.  If this argument is not specified, the specified instances
     of the search argument are replaced with a null string ("").

     <nStart> is the first occurrence that will be replaced.  If this
     argument is omitted, the default is one.  If this argument is equal to
     or less than zero, STRTRAN() returns an empty string.

     <nCount> is the number of occurrences to be replaced.  If this
     argument is not specified, the default is all.

 Returns

     STRTRAN() returns a new character string with the specified instances of
     <cSearch> replaced with <cReplace>.

 Description

     STRTRAN() is a character function that performs a standard substring
     search within a character string.  When it finds a match, it replaces
     the search string with the specified replacement string.  All instances
     of <cSearch> are replaced unless <nStart> or <nCount> is specified.
     Note that STRTRAN() replaces substrings and, therefore, does not account
     for whole words.

 Examples

     .  This example uses STRTRAN() to establish a postmodern analog
        to a famous quotation:

        cString:= "To compute, or not to compute?"
        ? STRTRAN(cString, "compute", "be")
        // Result: To be, or not to be?
