CALL 62 – Number to
String Conversion Purpose
Use CALL 62 to convert a number or numeric variable into a string. You must
allocate a minimum of 14 characters for the string. If the exponent of the value to
be converted is anticipated to be 100 or greater, you must allocate 15 characters.
Error checking traps string allocation of less than 14 characters only. There are no
output arguments.
Syntax
PUSH [number to convert to string]
PUSH [string number to receive the value]
