Description

The EXECSCRIPT() function runs multiple lines of code. The lines of code are contained in <expC>, which can be a text constant, a character variable, or a character or memo field. The EXECSCRIPT() function, unlike EXEC() can handle blocks of code, such as FOR...NEXT or DO WHILE...ENDDO loops. Individual lines of code must be separated by a CHR(13) carriage return character.

The EXECSCRIPT() function returns a logical true (.T.) unless its contents specifically return false (.F.).

Example

// Character field
create table scripts (script char(200))
use scripts
append blank
replace script with "for i=1 to 10" + CHR(13) + "?i" + CHR(13) + "endfor" + CHR(13)
execscript(script)
 
// Text constant
execscript("for i=1 to 10" + CHR(13) + "?i" + CHR(13) + "endfor" + CHR(13))
 
// Memory variable
m_script = "for i=1 to 10" + CHR(13) + "?i" + CHR(13) + "endfor" + CHR(13) 
execscript(m_script)
